The Selectively permeable Cell Membrane
Diffusion, osmosis, and active transport
• Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
• Osmosis occurs when water particles move from a higher concentration to a lower concentration
• Explain how placing this wilted flower in water will cause the flower to “straighten up”.
Example 1: Equal movement of water in and out of cells
Example 2: More water moving into cells than is moving out
Example 3: More water moving out of cells than is moving in
