Back

Diffusion

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the main difference between active and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells as water moves into it.

Front

What is the role of ATP in active transport?

Back

ATP provides the energy needed for active transport processes.
