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)

Objectives: 1) Explain how the processes of diffusion and osmosis occur and why they are important to cells. 2) Predict the effect of a hypotonic, hypertonic,

Let’s look at one example involving osmosis. Osmosis is the diffusion of water across a semi permeable membrane such as a cell membrane. A semi permeable.

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
