Question

give significance of mitosis 

Answer 1

The significance of Mitosis are :- 1. It is an equational division through which identical daughter cells are produced having the same amount and type of genetic constitution as that of the parent cell. 2. It is responsible for growth and development of multi-cellular organisms from a single-celled zygote. 3. The number of chromosomes remains the same in all the cells produced by this division. Thus, the daughter cells retain the same characters as those of the parent cell. 4. It helps the cell in maintaining proper size. 5. Mitosis helps in restoring wear and tear in body tissues, replacement of damaged or lost part, healing of wounds and regeneration of detached parts (as in tail of a lizards). 6. It is a method of multiplication in unicellular organisms. 7. If mitosis remains unchecked, it may result in uncontrolled growth of cells leading to cancer or tumour.

Answer 2

$\huge\pink{Mitosis}$

⭐ $\huge{ Growth }$

Mitosis is essential for the growtg and development of multicellular organisms. A fertilized egg develops into an embryo and then into an adult by repeated mitotic divisions.

⭐$\huge{ Cell size }$

Mitosia maintains the size of a cell. If a cell becomes large, then it enters into mitosis.

⭐$\huge{ Genetic Stability }$

Mitosis maintains the same type and number of chromosomes in two daughter cells.

⭐$\huge{ Repair }$

Mitosis replaces old dead cells by new cells.

⭐$\huge{ Reproduction }$

Mitosis brings reproduction in unicellular organisms like amoeba, bacteria etc.

⭐$\huge{ Healing }$

Mitosis produces new cells for healing the wounds and for regeneration.
