DIFFUSION IN CELLS • Substances such as oxygen can diffuse across the membrane of a cell. • Where will this oxygen go? 5% 20% 1% 12%

• Sometimes, particles are not able to cross the membrane, yet nature still progresses towards equilibrium (equal concentration on both sides). • How does this happen?

OSMOSIS • Sometimes, particles are not able to cross the membrane, yet nature still progresses towards equilibrium (equal concentration on both sides). • How does this happen?

OSMOSIS In osmosis, water moves from an area of low concentration to high concentration to even them out.

FILL IN THESE BLANKS • If a cell is surrounded by a fluid that has the same concentration as it does, the fluid is said to be ______ to the cell. No water will move. 32%

FILL IN THESE BLANKS • If a cell is surrounded by a fluid that has a smaller concentration than it does, then it is called _______. Water will move _______ the cell. 22% 9%

FILL IN THESE BLANKS • If a cell is surrounded by a fluid that has a greater concentration than it does, then it is called _______. Water will move _______ the cell. 8% 42%
