Osmosis | The movement of water from high concentration to low.
🗑

Equilibrium | When molecules are equally spread outand they move at equal rates in and out of the cell.
🗑
|
||||
Passive Transport | Movement across a cell membrane that requires NO ENERGY; diffusion and osmosis are examples of passive transport. Glucose moves into the cell by passive transport using a transport protein.
🗑
|

Active Transport | Movement across a cell membrane that REQUIRES ENERGY. Molecules move from low concentration (less crowded) to high concentration areas (more crwoded). Plant roots use active transport to move more nutrients in.
🗑
|
||||
Endocytosis | When large molecules, such as bacteria and preteins, ENTER the cell.
🗑
|
||||
Exocytosis | When large molecules, such as wastes from the vacuoles or proteins packaged by the Golgi bodies, EXIT the cell.
🗑
|
||||
Diffusion | The movement of molecukles (liquid or gas) from an area of high cencentration (More crowded) to an area of lower lower concentration (less crowded). There is no energy required, it is a natural sqreading out.
