Answer:
Cell division is important for growth,maintenance of proper chromosome number,wound healing
Explanation:
1 Cell division results in the formation of new cells which further undergo division to form new cells and so forth.Thus many cells are formed which are organized in tissues.Tissues then builds up organs and a number of organs builds up total body.
2 Cell division helps to maintain its chromosome number within the newly formed daughter cells.
3 Division of cells result in the formation of new cells in the site of wound and this accumalation of new cells in the wound region replace damaged and dead cells thus ultimately results in wound healing.
