Whats the cell theory?
|
1)All living organism consist of one or more cells.
2)Cells are the basic structures and organization of all living organisms. 3)Cells arise only from previously existing cells, with cells passing copies of their genetic material on to their daughter cells. |

|
Describe the plasma membrane.
|
It has carbohydrate chains, transport protein, polar heads, and non-polar heads.

|
What makes up most of the plasma membrane?
|

|
Is the process by which a cell sounds a substance in the outside environment.
