Front

What is osmosis?

Back

The movement of water across a semipermeable membrane from an area of low solute concentration to high solute concentration.

Front

What are the two types of transport across the cell membrane?

Back

Passive transport and active transport.

Front

What is active transport?

Back

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

Front

What is the role of mitochondria in the cell?

Back

To produce ATP, the energy currency of the cell.
