Give the three (3) reasons why cells undergo mitosis

Hello TierraNicole9864

Here are three reasons cells undergo mitosis:

#1: To reproduce -- mitosis is the way that cells reproduce and create their own "offspring" in order to repopulate.

#2: To restore dying cells -- mitosis is the division of cells in order to create new ones, and to replace these cells that are fading away.

#3:  To repair damaged cells -- cells divide themselves in order to help other cells that are not doing so well. 

Mitosis is a very important procedure that happens very often in many living beings.  

Hope This Helps!
