Front

What is the function of the cell membrane?

Back

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

Front

What are phospholipids?

Back

Molecules that make up the cell membrane, consisting of hydrophilic heads and hydrophobic tails.

Front

What is passive transport?

Back

The movement of substances across the cell membrane without the use of energy.

Front

What is active transport?

Back

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

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.
