Back

Passive Transport

Front

What is osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What is the main function of the cell membrane?

Back

To protect the cell and regulate the movement of substances in and out.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against a concentration gradient, while passive transport does not.

Front

What is exocytosis?

Back

The process by which a cell expels materials in vesicles.
