Question

Mitosis occurs in
a) Haploid individuals
b) Diploid individuals
c) Both (a) and (b)
d) In bacteria only

Answer 1

Hint: Mitosis occurs in the cell where the DNA is replicated and divided into two daughter cells. The mitosis occurs in four stages of prophase, metaphase, anaphase, and telophase. Prophase is the longest phase of the mitosis. Telophase leads to the cytokinesis of the cell.

Complete answer:
Mitosis is the equational division of the cell. It occurs in both the haploid and the diploid individuals. In this division, the number of chromosomes remains the same as the number present in the parent cell. In plants, the haploid cells divide mitotically to produce the gametophyte, and, in the plants, and animals having the diploid cells the growth occurs through the mitotic division in those cells. Mitosis is the process in which different stages are present in order to undergo division. These stages include the prophase, metaphase, anaphase, and the telophase stage. The prophase stage includes the condensation of the chromatin material and the disappearance of the nuclear membrane. In the metaphase stage, the chromosomes align themselves to the equatorial plate and in the anaphase stage, the chromosome separates and travels to the poles of the cells. In telophase, the division of the cells starts and the reappearance of the nuclear membrane can be seen. When the two daughter cells get formed it leads to the end of the mitosis.
So, the answer is ‘both a and b’.

Note: Mitosis is necessary for the growth of the cells in individuals. It helps in developing the cells which are identical to each other. Such identical cells are required by our body for growth and regeneration. The plants also use mitosis for their growth.
