(a) Mitosis:
It is important for:
• Increasing the number of cells in a particular tissue.
• Protection from harmful microorganism in case of a cut or wound.
• Replacing or repairing dead or inefficient cells in a tissue.
• To maintain the ratio of cytoplasm to nucleoplasm as well as surface area to volume.
(b) Meiosis:
• It is the most essential process in all sexually reproducing animals.
• Maintain chromosomal number in zygote (diploidity of zygote).
• Meiosis show crossing over, resulting in genetic recombination.
• Meiosis show a number of incidences of mutation (sudden changes in genetic material).
