1. The Cell Cycle

2. Why do cells divide? - Density Dependent Inhibition - - : - Obtaining:
- Obtaining -
Ridding themselves of -

3. Mathematical Proof: Surface Area Volume cm2 cm3 Compare:
Surface Area = 1x6(9) = 54 =
Volume x3x
Surface Area = 1x6 =
Volume x1x1
_______ surface area
per unit of volume
______ surface area
per unit of volume

4. Cell Cycle Mitosis:_________ Interphase: __________
So cells divide to stay small and efficient.
Let’s look at their life cycle:
G Phases =
