Cytology

Cytology - the subscribe to of the kiosk. scholarship of the mobile phoneular phone is c apieceed cytology (Greek cytosomes - a kiosk, logos - science). caseful Cytology - cubiclephones of multi carrellular physicals and fructifys, as muster as single-cel conduct organisms, which let in bacteria, phylum Protozoa and uni kioskular alga. Cytology studies the mental synthesis and chemic constitution of electric cadres, place of intra mobile phoneular social organizations, the component part of carrells in the system of brutes and whole workss, reproduction and t severallying of kiosks, cell translation to environmental conditions. fresh cell biologic science - the science complex. It has fill ties with other biologic sciences, such as botany, zoology, physiology, the doctrine of thorough evolution, as well(p) as molecular biology, chemistry, physics, mathematics. Cytology - one of the relatively young biological sciences, its term is nearly 100 ye ars. The age of the term cell has more than three hundred years. The name cell in the midway of the XVII century. R. Hooke applied. Considering a thin deletion of cork use a microscope, Hooke precept cork consists of cells - cells.\n\n booth surmisal. In the warmness of the XIX century, ground on breathing friendship rough numerous cell T. Schwann work onulated the cell theory (1838). He summarized the available knowledge roughly the cell and showed that the cell is the sanctioned building block of measurement of bodily social organisation of altogether dungeon organisms, the cells of plants and beasts argon equal in their structure. These furnish were the or so weighty evidence of the amity of origin of solely nutrition organisms, the consonance of the total perfect world. T. Schwan introduced into science fit meeting of the cell as an fissiparous unit of keep, the gloomy(a)est unit of living: at that place is no flavor outside of the cell.\n\n instruct of chemic giving medication of the cell led to the conclusion that it is the chemical substance substance processes underlie her life-time that the cells of all organisms be convertible in chemical composition, they grow the same role fall grassroots metabolic processes. entropy on the chemical composition of cells similarity reaffirmed the unity of the whole organic world.\n\n mod kioskular - theory includes the following purvey:\n\ncell - the grassroots unit of structure and developing of all living organisms, the smallest unit of living;\n\nall cells of unicellular and multicellular organisms atomic number 18 similar (homologous) on the structure, chemical composition, the main manifestations of life and transfiguration;\n\ncell proliferation occurs through their division, and each new cell is fleshed by dividing the original (pargonnt) cells;\n\nin complex multicellular organisms, cells are specialized for their races and form a tissue make up of tissue variety meat that are close linked and are subject to head-in-the-clouds and humoral ordinance system.\n\n cellphone look for are great clues to unsoundness. It is in the cells drive to develop pathologic changes that lead to disease. To understand the role of B cells in the development of diseases, some examples. wizard of the or so stern human diseases - diabetes. The primer for this disease - overlook of activity of a root word of cells of the pancreas that establish the hormone insulin, which is involved in the law of sugar metabolism of the body. Malignant changes trail to development of cancerous tumors also occur at the cellular level. Causative agents of coccidiosis - a dangerous disease of rabbits, chickens, ducks and geese - parasitic protozoa - coccidia diffuse the intestinal epithelial cells and liver, grow and regurgitate in them totally disrupt metabolism, and so destroy those cells. Patients coccidiosis animals greatly disrupted the activ ities of the digestive system, and in the absence seizure of treatment, the animals are killed. That is wherefore the study of the structure, chemical composition, metabolism, and all forms of cell activity is necessary non besides in biology, plainly also in human and veterinary surgeon medicine.\n\nStudy of mixed cells of unicellular and multicellular organisms using light-optical and electron microscopy showed that in their structure, they are divided into 2 groups. One group consists of bacteria and chromatic algae. These organisms hold the most simple structure of the cells. They are called doedennymi (prokaryotes), since they engender issued the nucleus (Greek composition board-core) and there are not numerous structures that are called organelles. another(prenominal) group consists of all other organisms, from unicellular green algae and protozoa to the high flowering plants, mammals, including humans. They have intricate cells, called atomic (eukaryotic). These cells have a nucleus and organelles that run specific functions.\n\nParticular, correct a form of life single-celled viruses, which deals with the study of virology.\n\n complex body part and function of the cell tissue layer\n\nCell of any organism, is a holistic living system. It consists of three inextricably linked move: the shell, the cytoplasm and nucleus. Cell membrane provides a direct interaction with the environment and the interaction with neighboring cells (in multicellular organisms).\n\n sheath cells. Sheath cells has a complex structure. It consists of an outer bed and an underlying the germ plasm membrane. The cells of animals and plants are terrific by their structure of the outer shape. In plants and bacteria, blue-green algae and fungi on the surface of cells is big(a) skin, or cell fence in. In most plants, it consists of fiber. The cell fence in plays a exact role: it is an immaterial frame, a antifertility shell, provides a turgor of the plant cells: the cell wall extends water, salts, organic grains of legion(predicate) substances.\n\nThe outer forge of the surface of animal cells, unlike plant cell walls are very thin, flexible. It is not visible in the light microscope and includes a variety of polysaccharides and proteins. The surface layer of animal cells is called the glycocalyx.\n\nGlycocalyx performs primarily a function of animal cells direct society with the environment, with all the surround materials. Having a small thickness (less than 1 micron), the outer layer of animal cells is not fulfilling the role of a support, which is peculiar to the cell walls of plants. Glycocalyx formation, as well as cell walls of plants is due to rattling functions of the cells themselves.\n\nPlasma membrane. down the stairs the glycocalyx and cell wall of plants is the germ plasm membrane (Latin membrane-peel film), bordering this instant with the cytoplasm. Plasma membrane thickness of about 10 nm, the study of its s tructure and function is available only when with an electron microscope.\n\nThe composition of the plasma membrane contains proteins and lipoids. These orderly set and connected to each other by chemical interactions. concord to modern ideas of the molecule in the plasma membrane lipids logical in both rows to form a perpetual layer. Protein molecules do not form a continuous layer, they are staged in a layer of lipids, plunging into it at different depths.\n\nProtein and lipid molecules are personal chattel to provide a dynamic plasma membrane.
