Why do animal and plant cells both rely on cell division
by mitosis?

Both plant cell and animal cell rely on cell division for their growth and development.

Explanation:

Cell division is very much important in case of both plant cell and animal cells because

1 Cell division helps in the transfer of genetic material from parental cell to the daughter cell thus playing a significant role in cellular reproduction.

2 We all know that cells are the structural and functional unit or basic unit of life.Cell division in case of both plant and animal result in the formation of new cells which further undergo cell division to generate new cells and so forth.Thus many cell are formed which together leads to the formation of various body tissues.

3 Cell divison also helps in wound healing.During wound healing the damaged cells are replaced by newly formed cells.
