1 The Selectively permeable Cell Membrane Diffusion, osmosis, and active transport

2 Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

3 Osmosis occurs when water particles move from a higher concentration to a lower concentration

4 Explain how placing this wilted flower in water will cause the flower to “straighten up”.

5 Example 1: Equal movement of water in and out of cells

6 Example 2: More water moving into cells than is moving out

7 Example 3: More water moving out of cells than is moving in

8 Active Transport (sugar)

DIFFUSION & OSMOSIS.

DIFFUSION & OSMOSIS.
OSMOSIS OSMOSIS: The diffusion of water through a selectively permeable membrane SELECTIVELY PERMEABLE: some substances pass like water and others do.

Osmosis and Diffusion Semi-Permeable membrane – allows some things through and keeps other things out (Also called selectively permeable)
