Growth and RepairOuch! My finger, my finger, get a tourniquet, no more cutting melons for me today! I hope this won't need stitches. To repair the damage that a knife cut or any wound causes, cells must divide and replace the dead and damaged cells of the wound. Even though a human body can't grow a whole new arm if one is removed, like a lizard can regrow a tail, it does have remarkable powers to replace injured cells. How does this happen? Where do all those cells come from? Anytime an organism grows or repairs a damaged or worn out part, new cells are being made. Cells reproduce by a process called mitosis. Mitosis is the process where a cell divides and the outcome is two identical cells. Move on to the BioVenture tab to continue this adventure.
