The tendency of a substance to move from an area of higher concentration to an area of lower concentration.

• diffusion

• osmosis

• active transport

• sodium-potassium pump

The movement of water through a membrane from an area of higher concentration to an area of lower concentration.

• sodium-potassium pump

The process of using energy to move materials through a membrane.

• diffusion

• osmosis

• active transport

• passive transport

The process by which green plants and other producers use simple compounds and energy from light to make sugar, an energy-rich compound.

• fermentation

• cell respiration
