• active transport

• endocytosis

Diffusion of water through a selectively permeable membrane.

• osmosis

• diffusion

• facilitated diffusion

• passive transport

Uses energy to move a substance across a concentration gradient from an area of low concentration to an area of higher concentration.

• diffusion
