Question

What is meant by the term cell division? Why is cell division necessary?​

Answer 1

Explanation:

Cell division is the process by which a parent cell divides into two or more daughter cells.[1] Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of cell division; a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).

This process helps in:

Renewing of damaged cells.

Production of new cells from older ones.

Maintains the total number of chromosomes.

Provides more cells for growth and development.

Repairs and controls damages caused to the cells.

Also helps in survival and growth of living organisms.

It is responsible for a definite shape, size and proper growth and development of an individual.

In plants, mitosis helps in the formation of new parts and in repairing the damaged parts.

Answer 2

Answer:

$\huge\bold\red{AnsWer}$

Cell division is the process of formation of two daughters cells by the division of the parent cell. It is of three types:

1. Mitosis
2. Meiosis
3. Amitosis

Cell division is the most important process for living organisms without which life is not possible. There is much significance of cell division but few are as follows:

• Cell multiplication - Formation of new cells from older ones.
• Life continuity - Continuation from one generation to another.
• Growth - The division of cells increases the growth of an individual.
• Size - Required size is obtained.
• Reproduction - Formation of a new organism from older one through meiosis.
