Front

Diffusion is a form of __________.

Back

Passive Transport

In which solution will water move into a cell?

Back

Hypotonic

Front

What are the three types of passive transport?

Back

Diffusion, osmosis, facilitated diffusion

Front

Diffusion is the movement of molecules from __________.

Back

An area of high concentration to an area of low concentration.

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 membrane without the use of energy.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses protein channels to help move molecules across the membrane.

Front

What happens to a cell in a hypertonic solution?

Back

The cell shrinks as water moves out.

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells as water moves in.
