Ahh, life at the Lots-O-Palms Oasis. Fresh dates with cream cheese and some cool water; it doesn't get any better than this. Well my friends, it's almost time for us to part ways; much like when a mature cell divides, we must part, take our knowledge, and spread it across the landscape. Just a minute, and I'll cut up some of those melons; they're so refreshing on a hot day.
Let's check out our map below to make sure we stay on the right path as we head back to the bus terminal.

Growth and Repair
Ouch! 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.
