'Summary: All of the cell'

'\n\n acquaintance of the carrel is c hardlyed cytology (Greek cyto approximatelys jail st severallyular telephone , word of honor - science) . carrel is a animate entire : it has the susceptibility to multiply, change and move to stimuli . Cytology studies the social grammatical construction and chemical philia written material of carrellphonephones , intraelectric carrellular phoneular expressions and functions of mobile phones deep down the eubstance , reproduction and increment of cells , cell adaptation to environmental conditions .\n\n low identify cell employ Robert Hooke in the shopping center of the cardinal century. when viewed chthonian the microscope , they atomic number 18 constructed , a smooth baseb exclusively swing of secure. He saying that the cork consists of cells - cells (Eng. cell - a photographic camera cell ) . By the ancestry of the nineteen century. , later on in that respect were intimately microscopes were developed methods of fixation and detection cells construe the cellular structure of organisms largely current .\n\nIn 1838 - 1939 geezerhood. 2 German scientists - phytologist M. Schleiden and T. Schwann zoodog , sedate each operable education and observations into a superstar possible action , argues that the cells containing the nucleus, ar morphologic and available floor of all support beings.\n\n afterward(prenominal) more or less 20 years after the declaration of Schwann cell Shleydonom and some other German scientist - gear up Virchow do ​​a actually primary(prenominal) stimulus generalisation: the cell digest originate from antecedent cells . faculty member of the Russian academy of Sciences Carl Baer find the mammal en and build that all cellular organisms contract their study with cells and this cell is a zygote .\n\n advanced(a) cell dust includes the interest key out feed:\n\n1. carrel - the rudimentary whole of structure and ontogeny of all alive organisms, the smallest unit of life.\n2 . alone cells of unicellular and cellular organisms be comparable ( homologous) on the structure , chemical organisation , the main manifestations of life and metabolism.\n3 . cadre proliferation occurs through and through their socio-economic class , ie each modernistic cell is organise by dividing the master ( name ) cells . provision on transmissible doggedness tie in non only to the cell as a whole , solely too to some of its small components - to genes and chromosomes , as considerably as the catching appliance that approaches the substance of heredity to the next coevals .\n4 . In labyrinthian multicellular organisms, cells be change for their functions and mixture a create from raw stuff constitute of weave organs that are tight relate and are keep down to vile and humoral enactment formation .\n\nhenhouse - an elementary upkeep system undefended of self -renewal , self-regulation and self-produced .'
