|
growth
|
-Limit to cell size

-what does it do to the size?
-why do they need to divide? -how is cell division important for cells? |

-repair of injuries |
who repairs and why?

|
passage of chemicals through the cell membrane from an area of higher concentration to one of lower concentration.
|
|
