What is Metamorphosis? ~ Biology

What is Metamorphosis  insects and frogs

Metamorphosis, insects, frogs, some species, such as leaving the eggs of the next growth phase undergoes structural changes, it becomes similar to their ancestors.

 

   Many animals, in unstable conditions during development into pupae survive through the preserves.Complete return to normal development of the media and becomes mature.
   Larval stage of metamorphism, larvaya consists of the organs. Groups of cells in the adult universe, waits for the larva stage of development. These events are controlled by hormones. Metamorphosis insects, juvenile hormones and plays a role in ekdison. Ekdison hormone, both larvae and pupae and adult stages need to change the skin and allows the occurrence of Metamorphosis. If juvenile hormone, prolongs the period of larval insects.
   In animals, the conversion, the full and half-seen in two ways.
Half Transfiguration: This type of living creature metamorphosis, passing through the maturity of the youth observed very little change. These creatures, while the mature form, similar in young, but still very small, wingless, and gender is not developed. As an example, grasshoppers can be given.
Full Metamorphosis: state of larval period, major changes occur until adolescence. A complete metamorphosis, butterflies, moths, flies, etc.. As is seen in insects. This species, the larva or caterpillar is in the wolf periods (depends on the type). They are not like adult become. A number of feathers, leather, etc.. is a result of shifting operations into pupae. At the end of the next development events are transformed into mature individuals.

   

Ekdison hormone, juvenile hormone if the larvae than the dominant, the skin will continue to change. First, pupae, and then become mature. So ekdison hormone provides early metamorphosis.
   If the juvenile hormone-secreting gland is removed, the larvae mature individuals early Metamorphosis and consists of a dwarf.
 Metamorphic frogs   Frogs metamorphosis, the thyroid gland is provided by the hormone thyroxine. If the frog larvae, and small amounts of thyroid extract, thyroxin is given immediately, and the land is transformed through the dwarf consists of an adult individual. If, however, be issued by the thyroid gland in larvae, larvae of animal remains in continuous and life continues in this way.
   Many changes occur during metamorphosis frogs. Larvadaki; tail, pronefroz kidney, gills, mouth parts and the adults instead of losing the function of a cell glands mezonefroz kidney, lung, and consists of many cell skin glands. Herbivor larval period (grass fed), the live, in adult carnivores (meat-fed) diet, and again passes through the teeth of the jaw develops.
   Physiological changes observed during metamorphosis. Larvae in the water of oxygen that can hold period hemoglobins, connect the black life, the gaseous oxygen. However, amino acid metabolism as a result of larval period, rather than waste materials are ammonia, which is less toxic than in adults, and occurs with less water dilutable urea. However, vascular layer of the pigments in the eyes that see the past in the water, on land that opinion will change

What is Tissue? ~ Biology

What is Tissue? Tissue 

Tissue, plant, animal and human organs that occur, are similar in terms of shape and structure, which the same task, each collection of cells from the same root with tight alâkaları. Primitive forms of life even though their whole lives in a single cell with higher organisms consists of a large number of cells come together.

 
Crop Nutrient Media organisms that make up a large number of cells separated from each other, although non-viable cell çeperleriyle shows a strong relationship between them. Found in such cell wall, showing the close contact with each other, have come from the same root protoplasts communities tissue, the morphology of the science branch of the subject properties of the tissues in the histology (tissue science) is called. Cells that make up the texture is usually seen in front of the paper describing the basic ideas and tissue görmekteyseler morfolojikseldir rather than physiological. If you do recipe tap fizyolojiksel respect, even if the origins of different cell populations in the same paper which was to be done, so the wider community of cells is called tissue systems. Tissue occurs as a result of cell division. Single-celled organisms, dividing cells were separated and brought new individuals in their body, even though the cells of multicellular organisms, cell divisions that occur not separated from each other, passages and plasmodesma (plasmatik bridges) with such materials and structures that facilitate the transmission of superframes proplastları established close relation between the individual cell populations constitute the . In some circles, are combined into a single-celled mucilage broken into groups of cells held together by a sheath and a braid of some mantarlardaki rich branching to form filamentous cells are often in clusters, in terms of external appearance of tissue texture andırsalar not even real, pseudo-tissues. Into two separated tissues, including plant and animal tissues examined. Contents 1 1.1 Plant tissues Meristem tissue (divided, constantly, sürgen, variable tissue) 1.1.1 a) Primary Meristem (primary) 1.1.2 b) Secondary Meristem (posteriori) 1.2 Continuous tissue (tissue MMORPG) 1.2.1 Protective tissue (Central Department of the cell, ie co (eng), to be found in? 1.2.2 parenchyma (base tissue) 1.2.3 Support 1.2.5 texture 1.2.4 Transmission of tissue Epithelial tissue Glandular system 2 3 connective tissue of animal tissue 2.1 3.1 3.2 Nervous tissue Blood Plant tissues that make up the structure of plant tissue, reproductive tissue, 03/03 tissues is called the plant tissues. farklılaşmışlardır as advanced plant cells organized into tissues. agglomerate into two basic groups: Meristem tissue (divided, constantly, sürgen, variable tissue) Meristem cells, the nucleus of cells from large gaps non-malignant cells were often very small and a large number of vacuoles. This is the main feature of the cells often divide (mitotic division) of new cells in our series. The resulting cells differentiated tissue cells becomes constant. meristems names are on their location. root, stem, or in their subsidiary organs of the ends of the meristem is called the meristem tissues apiteal. Stem or provide the body reaching. İnterkalar meristems meristemlerdir between the permanent tissues. İnterkalar meristem length of the organ to grow in the task. Meristematic environment that allows the growth of transverse parallel divisions organ tissue and meristems of lateral meristem kambiyumdaki . any plant meristem is lost in search of substance, the auxin hormone secreted by alır.Meristemlerin meristems task in the dark trying to allow the development of the plant on and on. a) Primary Meristem (primary) during the entire life of the plant's ability to sustain meristemlerdir division. They are the root and stem ends of the edge parts of the lateral organs. This meristem regions where the "growth points" or "vegetation zones" are called. Root and stem the growth points in the three regions are distinguished from outside to inside. These regions make up the epidermis tissues constantly "dermatogen", the cortex will be a 'periblem ", the central cylinder, which will" pleurom "stop. b) Secondary Meristem (posteriori) Continuous tissue cells are transformed into the ability to win the division again occurs with the secondary meristems. Effectiveness of these new cells and tissues occurs with. For example, this type of tree trunks kambiyumu meristems is one that covers the cork. Meristem of plants observed in 3 types according to place of Occurrence. Apical meristems: These are the roots and stems, their lateral organs meristemlerdir in the end. Regions where the growth points are called apical meristems. İnterkalar meristems: Always show the division between these tissues and cells between tissues meristemlerdir formed. This is typically at the tails of meristems and leaves of cereals are found in regions where. NOTE: the organ in which the apical meristems and interkalar uzamalarını provide stature. Lateral meristems: the organ in which they reflect the division of these meristems çapça growth only parallel to the environment (thickening) provides. Continuous tissue (tissue MMORPG) Divide large vacuoles in cells of meristem tissue cells possess permanent property is not present, less protoplasm shipments, and sometimes even lost altogether protoplastlarını getirmeleriyle become separated from the dead. Walls are thick, the thickness of different tissues and different chemical structures. Continuous tissue, taking into account the morphological and physiological characteristics can be examined at the five classified.Protective tissue (ie, co Department of the cell medium (eng), to be found in? Of organs located outside of the inner tissues and in all respects, for example, drought, too much water loss, is the tissue that protects against external influences. This is the tissue of organs that constitute the top of the layers of cells, usuallycovers. epidermis in leaves, roots, and mushroom bodies in the protective tissue layers are shown as example. leaves are waxy layer called cutin on the epidermis. leaf surfaces reduce water loss, as well as the external environment to the cell below the epidermis and the cavities of gases collected from the plant as a result of the physiological activity of some of the gas and the purpose of providing the exchange of water vapor in the pores, called stomata are epidermada. Again epidermis outward on the epidermis caused by a feather, has rough edges, such as swelling. parenchyma (basic structure), original textures and structure of vegetation that covers a large portion of the thin-walled living cells. Food Vacuoles filled with rich juice containing material found in all parts of ederler.Bitkinin is named for. Duties will receive different names depending on: assimilation (Assimileme, assimilation) parenchyma due to substance chlorophyll organic material makes up the face of Light. the leaves are. (gives the leaf its green color .) Ventilation parenchyma (Aerankima) the exchange of substances between cells and the external environment in terms of providing a very wide gaps between cells called the owner of parenchyma cells. Marshes are plants. Forwarding Forwarding parenchyma with thin-walled parenchyma cells, tissue assimileme parankimasından conductive materials up to a large number of narrow cells in assimilation phased out by collecting a small number of cells in a wider transmission path reduces the number of peripheral resistance by reducing geçişmedeki provides. Storage parenchyma cells of parenchyma sometimes need different nutrients in the water need to do your homework as a backup storage. Support tissue Plants and their weights, as well as protect properties against external influences, resistance of certain tissues to become resistant to the elements by putting the necessary areas, provide support and flexibility. more thickened walls composed of such resistant cells is called tissue-supporting tissue. Sklerankima and examined in two parts in the collenchyma. Sklerankimayı maturity together with the cells and thick cell walls and the majority odunlaşmıştır. Protoplastlarını lost its dead cells. elongation has ended and organs. Collenchyma the flexible walls are made of cellulose, which lingers to be composed of living cells in organs, especially the young bodies, secondary veins of leaves, flowers and leaves have stalks. Corner kollenkiması, such as plate kollenkimasıThere are varieties of black life ... the transmission of tissue followed the high ground away from plants, soil, water and substances dissolved in water in the organs asimileme (assimilation) or storage organs occurring organic materials to be used in the organic substance which is incapable of making, is the tissue that allows the transmission of the organs. Plants from each other There are two types of conductive tissue of different structure and mission. This is one of the two tissues where the ground water and soil inorganic substances dissolved in water to distant organs has cells that transmit ksilem'dir. The other organs of assimilation occurring organic compounds containing harcanacakları and stored on-conducting cells floem'dir organs.bottom-up the xylem, phloem tissues from top to bottom where transmission occurred. xylem water-conducting tubes, xylem (fiber) s and xylem were parankimasından. Phloem, Kalburlu pipes, a friend of cells, including phloem parenchyma and phloem sklerankiması elements occur in different tissues. honeydewmetabolic system in plants at the end of the secretory substances in the ingredients are not coming back in metabolism. Glandular substances are solid or liquid. Secretion of substances water, ferment, alkaloids, glycosides, nectar, mucilages, latex, resins, oils and crystals include the etheric. These substances, althoughmetabolic waste if they also play a role in providing benefits to the plant in different directions. Glandular substances are stored or in the cell. It is called salgıya intracellular secretion. Or, is thrown out of the cell. It constitutes the secretion of the extracellular secretion. Glandular cells and these cells in a There is no coming together constituted the origin of certain endocrine glands. any organ of the plant, can be found in any tissue. Animal tissues are classified into five groups of animal tissues can be examined: epithelial tissue covering the surface of the body and the spaces in the body cells, which limit the mask layer, and consists of a continuous . protection, absorption, secretion, and sensory tasks, such as saw. the body's epithelial layer, the lower mechanical damages cells, harmful chemicals, bacteria and protect dry. other epithelia as a wide variety of waste products or secretions of the body which secrete substances used in another place. Epithelial tissues According to the form and functions are divided into sub-classes: sensory epithelium Glandular epithelium epithelium covering the connective tissue derived Mesenchymal connective tissue with a tissue, connects all the tissues. nutrition, protection, filling the interstitial spaces of the oil storage, the production of blood cells, and tissue protection against infections Provides repair. Connective tissue ground substance, composed of cells and fibers. Lower classes is divided. Embryonic connective tissue connective tissue connective tissue General Adult Mesenchymal connective tissue mucous connective tissue connective tissue connective tissue loose connective tissue, the regular tight tight tight irregular connective tissue connective tissue Private connective tissue Elastic connective tissue Reticular connective tissue Fatty tissue pigment of red and white blood cells, blood tissue blood tissue and blood gets into the non-cellular portion of the liquid. This liquid is called plasma. Sometimes, this tissue can be classified as connective tissue cells, because a similar arterial origin alır.Kan venous and capillary vascular network is composed of fluid plasma and cells circulating puts it occurred in a vital sıvıdır.plazmadaki red color is removed from the serum fibrinogen, white blood cells after red blood cells at the bottom kalır.Kanı santifrüjlediğimizde remains the most üctte flakes, and then a little bit of blood plasma and related medical terms kalır.Blood haemo usually begins with the words, and words hemoto karşılıyan haimoden the word is derived from the ancient Greek blood. Nerve tissue is made by cells called neurons. These electrochemical nerve impulses to transmit özelleşmişlerdir. Each cell nucleus, which contains an enlarged cell body and extending to the hair cells, similar to the has one or more very thin nerve fibers. Nerve fibers cytoplasm (cell plasma) made from the plasma membrane and is covered. This is the membrane thickness 30-40 micron, 1-2 millimeters in length can vary up to 1 meter lengths. In humans, the spinal cord to the leg or arm, uzananlar 1 meters or longer can be. There are two types of nerve fibers: axons and dendrites. They normally transmits nerve impulses can be distinguished based on the direction. Axons are nerve impulses away from the cell body, cell body, dendrites correct. of a neuron's axon and the other is called dendritic synapses in the intersection of . synapses, the impulse it serves as a valve preventing back flow görür.sinir cell bodies in CNS gray matter and nuclei in the ganglia of the PSS yerleşiktir.Sinir ... Reproductive tissue cells form extensions of the current ore to produce the female egg cells and altered sperm cells in males is called the tissue. egg cells and inert majority, round or oval. Sperm cells are smaller than egg cells. Stoplasma has lost most of the movement which he developed a queue is provided.

What is a Cell Division? ~ Biology

Cell division
Cell division is the process that cells go through in order to divide. Cells may divide for several reasons, and there are two types of cell division depending on the purpose. The cell divisionassociated with sexual reproduction is one type, called meiosis. The other type, the celldivision associated with growth and cell replacement or repair, is called mitosis. In both types of cell division, the nucleus splits and DNA is replicated.
Three types of cell division cell division, the proliferation of single-celled organisms, the growth of multi-celled organisms, male and female gametes to ensure that the biological event occur.

To split a cell reaches a certain size should have, and nucleic acids. The living world, Amitoz (Amitozis).Mitosis (Mitozis) meiosis (Meiosis) has three different types of division. Single-celled organisms usually amitoz division, mitosis and meiosis occurs in many-celled. Usually seen in single-celled species Amitoz that this split will increase the number of individuals.
Amitoz division of cells that extends the kernel, the kernel is divided into two taller, with the nucleolus in the long-drawn boğumlanarak. Following this, the division of the cytoplasm of a cell division occurs to consist of two new puppies. Amitos  nuclear envelope is not lost, it does not appear to chromosomes, spindle fibers attach to spindle fibers does not occur. Some special cases outside the highly structured, single-celled organism can be seen in the cells amitoz. In this case, the cells often are sentenced to death, because they can not re-mitosis. Division in cells that degenerate in this organism due to hunger Amitoz sometimes, some of the older cartilage cells, also seen in cells proliferating in the bird embryo blastoderm. Gametes are usually not seen amitoz division. Mitotic cell division is a phenomenon seen in all living things.
The purpose of this event live or in cell division takes place, depending on the cell to form new cells, to ensure renewal and growth. In addition, some organisms, such as eggs and sperm to create sex cells. Prior to the division of a cell, the cell must reach a certain size. Cell division and proliferation of a cell creatures, male and female sex cells, the growth of multicellular organisms required for the occurrence of an event.Mitotic cell division of body cells, including germ cells, to create a meiosis takes place in two different ways.

Animal  Cell Division

During cell mitosis, as shown in the top division in mitosis through consecutive stages that different to be considered a single-celled growth, is used for multi-celled growth. Healing of injured cells in mitosis and is worn with. Chromosome information consisting of the same cells. During the rapid growth of mitosis. Nerve, the sperm and egg cells, mitosis is not.

What is a Cell? ~ Biology

Atomic building block of matter, the building blocks of all living things in the cell in the universe. Single-celled organisms, all vital activity and ends in a single cell. Groups of cells within multicellular organisms form different structures etmesiyle tissues, organs, tissues come side by side, to a combination of organs, systems, systems of the organism occurs in the community. Thus, each cell of the organism to be a certain task in a system with lirli tavzif would have taken place as is.


Cells are living in a social subject. Cells with other cell populations, in community with other communities made on the basis of each cell are found in the relationship. Dependent on the cells located within each community, a balance that is vital cells are found in other communities. Without disturbing the harmony of each cell through the cell alakaları made on the basis of this universe of billions of living things act in accordance with current laws Traditional magnificent vital activities of cells with different forms and serve as mutual assistance, solidarity, unity and togetherness is provided with.

What is the Population? ~ Biology

Population, density and distribution of digital assets of all kinds live. Although the population for English as the term is frequently used in biology and sociology.

Population: a collection of individuals belonging to the same species living within a specific region. Genre:Capable of producing offspring from a common ancestor mate productive individuals.

What is a Gene? ~ Biology

Gene - BiologyGene, a unit of heredity. Genome sequence of identifiable location, transcribed, regulatory and / or the functional areas of a region. 
With the complexities of gene regulation and transcription, according to a new gene and a recognition of the self, "the same class (protein or RNA), functional products that encrypt, potentially overlapping, the combination of genome sequences." Gene, the basic physical and functional unit of heredity. Every gene, protein or RNA molecule with a specific function, such as the nucleotide sequences of chromosomes consists of a certain point. Classical genetics, the same biological functions according to deter them to a not managed and mutual recombination of alleles and genes are not allelic. Allelic genes, genes that are effective on the same property. Classical genetics the gene is used as a sub-unit.
