🔬 What is Cell Division?

Cell division is a biological process in which a parent cell divides to form new daughter cells. It is an essential process for the survival of living organisms.

In unicellular organisms, cell division is the method of reproduction.

In multicellular organisms, cell division helps in:

Growth of the body

Repair of damaged tissues

Replacement of old or dead cells

Formation of reproductive cells

Without cell division, life as we know it would not be possible.

🧬 Importance of Cell Division

Cell division plays a crucial role in maintaining life. Its importance can be understood through the following points:

✔️ Helps in the growth and development of organisms
✔️ Repairs injured or damaged tissues
✔️ Replaces worn-out and dead cells
✔️ Maintains chromosome number in species
✔️ Produces variation in sexually reproducing organisms
