Cell Cycle and Cancer Review

  1. What are three reasons why cells divide?

a. to repair tissue (multicellular organisms- like us)
b. to grow (multicellular organisms- like us)
c. asexual reproduction (unicellular organisms- like bacteria)

2) Why are cells so small?

Surface area to volume ratio is high when cell is small

It is easier for cells to transport materials and it decreases demands on DNA

Large ratio is desired (Ex: 1,000,000/1) because lots of surface area help materials get into and out of the cell QUICKLY and little volume is desired because it slows down the movement of these materials.
