Back

The movement of molecules across a cell membrane without the use of energy.

Front

What is diffusion?

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the role of the cell membrane?

Back

To protect the cell and regulate what enters and leaves.
