Osmosis

Osmosis is the diffusion of _____ across a selectively permeable membrane.

• food
• air
• water
• oxygen

During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

Ideally, your cells should be in a(n) _______ solution

• isotonic
• hypertonic
• hypotonic
• isometric

• osmosis
• equilibrium
• diffusion
• hypertonic
