Cell division phases

  1. Cell division
    A single cell divides many times and forms a multi celled organism unicellular bacteria and protozoa divide and increase in number the injured tissue are replaced by new cells through cell division division is one of the most important in all organ majority of cells in a multicellular organisms grow and then can divide however the cells like the nerve and muscle cells of animals and guard cells of plants do not divide the process of cell division is almost CM in all organisms a cell passes through stages of growth after which are able to duplicate their chromosomes before they divide these pages in the life of a cell constituting the cell cycle the cell cycle
    Mother aur parent cell food the cell that undergoes division and the daughter cells for the ones that are the result of distribution for each daughter cell undergoes division it must grow to the same size as its mother cell we can distinguish to main pages in the life of a cell enterprise non dividing period growth page dividing page also called M page M4 mitosis or meiosis
    Enter barabar in between the interval between two successive cell divisions is termed interfered page at which the cell is not reading it is the longest period in the cell cycle interface is subdivided into three main periods Jivan S and z to Z one get one page IE first page of growth this is the longest page lot of protein and RNA are synthesized during this this page
    For synthetic feel it comes next lot of DNA is synthesized a chromosome contains a single double helical strand of DNA molecule after aspx page is chromosome becomes longitudinally except at centromere and it has two molecules of DNA and two chromatids does is chromatid contains one molecule of DNA the two chromatids are joined by a centromere which does not divide at this stage to form a single chromosome
    Jeetu gap 2 phase more protein including the histones are synthesized in this page cytoplasmic organelles such as mitochondria and Golgi bodies get duplicated centriole also divides into two centrioles contained in a single centrosome
    MPS all dividing page
    Represented by the symbol a mitosis or meiosis mitosis occurs so that during this period the chromatid separate and form daughter chromosomes the mother the daughter chromosomes go to daughter nuclei and cytoplasm divides forming tool identical daughter cells
