Made of 2 membrane layers (phospholipid bi layer), it has protein on and embedded within it. (helps with cell identification and transport of some materials through the membrane) |
|
|
Semipermeability |
Will allow some materials through it, but not all. |

Type of Transport: Passive |
-Free and doesn't require energy -Relies on concentration gradients |
|
|
Type of Transport: Active |
-Requires energy to more large/charged molecules - To move them against their concentration gradient |
