which division is necessary to maintain constant chromosome number in all body cells of multicellular organisms organism and why?
Answers
Answer:
please mark me as brainliest answer and follow me.....
Explanation:
Mitosis is necessary to maintain constant number of chromosomes in all body cells in
multicellular organisms because mitosis results in the production of diploid daughter cells
with genetic employment usually identical to that of the parent cell. The growth of
multicellular organisms is due to mitosis. Cell growth results in distributing the ratio between
the nucleus and cytoplasm. It is therefore, essential for the cell division to restore the nucleo
cytoplasmic ratio. A very significant contribution of mitosis is cell repair. Mitotic divisions
in the meristematic tissues, the apical and the lateral meristems, results in a continuous
growth of plants throughout their life.
1. Mitosis is necessary to maintain constant chromosomes number in all body cells of multicellular organisms.
2. Because mitosis results in the production of diploid daughter cells with genetic employment usually identical to that of the parent cell.
3. Mitosis maintains a constant number of chromosomes in all the cells of the body.
4. Mitosis helps in wound healing and regeneration of plant parts.
5. The daughter cells formed by mitosis are identical with the mother cell.
6. Growth in organism is caused by mitosis and it restores the surface to volume ratio of the cell.
