What happens during osmosis?

Back

Water moves from high to low concentration.

Front

What is the diffusion of particles through the cell membrane from high to low concentration called?

Back

Back

Osmosis.

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is passive transport?

Back

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

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.
