The diffusion of water across a membrane is called

• equilibrium.
• osmosis.
• facilitated diffusion.
• active transport.

Diffusion is the movement of molecules from

• an area of equilibrium to an area of high concentration.
• an area of low concentration to an area of high concentration.
• an area of high concentration to an area of high concentration.
• an area of high concentration to an area of low concentration.

Cells sometimes use energy to transport materials across the cell membrane.  This is called

• photosynthesis
• osmosis
• cellular respiration
• active transport
