Active Transport |
when energy is needed for a substance to move across a plasma membrane. |
|
|
Diffusion |
the movement of a substance across a membrane, due to a difference in concentration, without any help from other molecules. |
|
|
Endocytosis |
the type of vesicle transport that moves a substance into the cell. |
|
|
exocytosis |
the type of vesicle transport that moves a substance out of the cell. |

Facilitated Diffusion |
Diffusion with the help of transport proteins. |
|
|
Osmosis |
the diffusion of water molecules across a membrane. |
