Understand why cell division is crucial for growth, healing, and reproduction in organisms. Explore how cells replenish and multiply to maintain and repair bodily tissues. Discover the varying rates of cell division in different parts of the body.
E N D
Healing & Tissue Repair • Every second millions of your body cells are injured or die. • If it wasn’t for cell division replenishing those cells your body would shrink and eventually die.
Growth • Cell division allows us to grow. • As we grow we increase in the amount of cells we are made up of and not the size of our cells. • Cells must maintain a certain size to survive.
Reproduction • Cell division plays a large role in the reproduction of both unicellular and multicellular organisms.
