Back

Active Transport

Front

In passive transport, molecules move from an area of __________ concentration to an area of __________ concentration.

Back

high, low

Front

What type of cellular transport is represented by the process of a cell expelling materials?

Back

Exocytosis

Front

Using a cell's energy to move particles is an example of what?

Back

Active Transport

Front

What is the process called when water moves across a selectively permeable membrane?

Back

Osmosis

Front

What is the main difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.

Front

What is facilitated diffusion?

Back

A process that helps molecules cross the cell membrane with the assistance of transport proteins.

Front

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

Back

It acts as a barrier that regulates the movement of substances in and out of the cell.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and may shrivel.
