Write briefly the significance of mitosis and meiosis in multicellular organisms.
Ans.
Significance of Mitosis:
Mitosis facilitates the development of single-cell zygote into a full-grown organism. It helps growth of an organism. It helps repair worn out or damaged tissues. It helps vegetative propagation in flowering plants. It helps regeneration in some animals.
Significance of Meiosis:
Meiosis makes sure that the number of chromosomes becomes diploid in gametes. This aids in making sure that the conservation of particular chromosomal numbers in species. Meiosis helps genetic variability in populations. This happens due to crossing over during prophase–I.
