Question and answer
when do organisms use mitosis
Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. [ It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of
the cell cycle?the division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell. This accounts for approximately 10% of the cell cycle. Mitosis occurs only in eukaryotic cells and the process varies in different species. For example, animals undergo an "open" mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi such as Aspergillus nidulans and Saccharomyces cerevisiae (yeast) undergo a "closed" mitosis, where chromosomes divide within an intact cell nucleus.[1] Prokaryotic cells, which lack a nucleus, divide by a process called binary fission. ]

User: when do organisms use meiosis

Weegy: when is meiosis process used? Meiosis in Animals Used to produced the gametes: sperm and eggs Meiosis in Plants Used to produce spores. [ Spores are the start of the gametophyte generation which, in time, will produce gametes (by mitosis because the starting cells are already haploid). Here is a brief overview of the process. A more detailed view is provided below. When the chromosomes first become visible they are already doubled, each homologue having been duplicated during the preceding S phase. Result: pairs of homologous dyads each dyad consisting of two sister chromatids held together by a protein complex called cohesin. Pairing: Each pair of homologous dyads align lengthwise with each other. Result: a tetrad. (These structures are sometimes referred to as bivalents because at this stage you cannot distinguish the individual sister chromatids under the microscope.) The two homologous dyads are held together by one or more chiasmata (sing. = chiasma) which form between two nonsister chromatids at points where they have crossed over. the synaptonemal complex (SC), a complex assembly of proteins (including cohesin) ]

User: in which process does the important difference occur





Weegy: ell division and reproduction can occur in two ways - mitosis and meiosis. Mitosis is a process of cell duplication, or reproduction

What types of cells and organisms undergo mitosis and meiosis?
Weegy: Mitiosis undergo cells and organisms that can reproduce asexually and create indentical copies of their DNA. Meiosis uses organisms that rely on sexual reproduction however the process of mitosis is still needed for growth. (More)
