Biology
Cell Cycle and Cancer Review
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.
What are three reasons why it is important for cells to stay so small
