Front

What is the role of the cell membrane in cell transport?

Back

It regulates what enters and exits the cell, maintaining homeostasis.

Front

What is active transport?

Back

The movement of materials against a concentration gradient, requiring energy.

Front

What is passive transport?

Back

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

Front

What is an example of diffusion in everyday life?
