Amitosis



  • How is amitosis different from mitosis? How can amitosis occur in cells of mammalian cartilage, foetal membrane and endosperm cells of seeds?

    All of these contain proper chromosomes but amitosis occurs without differentiation of chromosomes. Please explain.

    Is amitosis an equational division like mitosis? Do the two daughter cells receive exactly the same genetic material? Are daughter cells identical to the parent? Then how is it different from mitosis?



  • @anag
    amitosis is cell division by simple cleavage of the nucleus and division of the cytoplasm without spindle formation or appearance of chromosomes



  • @sunitasaxena Is amitosis an equational division like mitosis? Do the two daughter cells receive exactly the same genetic material? Are daughter cells identical to the parent?



  • @anag
    During the division of cells in amitosis the chromatin fibres does not replicate as in mitosis. The genetic material does not get equally distributed when the nucleus divides into two nuclei. Thus the two daughter cells does not look identical.



  • @sri then how are clones produced in a bacterial colony?



  • @anag bacteria divide asexually By binary fission in which their cell divides into two identical daughter cells...The identical products of asexusl reproduction are called clones



  • @anag
    binary fission is similar in some ways to the mitosis that happens in humans and other eukaryotes. In both cases, chromosomes are copied and separated, and the cell divides its cytoplasm to form two new cells. ... For one thing, no mitotic spindle forms in bacteria....Which makes it a amitotic division



  • @sri
    Binary fission is amitotic cell division
    Amitosis is also a Cell Division,which is commonly called as Direct Cell Division. It is a cell division by simple cleavage of the Nucleus and the division of Cytoplasm without the Formation of Spindle Fibres
