Why do cells need to divide?

They need to divide because thats how they reproduce.

Explanation: By the cells dividing, they are reproducing. When they reproduce the organism gets bigger, and that is how organisms grow.

Cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger.

Explanation:

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
