DIFFUSION & OSMOSIS.
Osmosis Osmosis is the net movement of water molecules over a partially permeable membrane from an area of less osmotic potential to an area of more negative.
Transport of substances across a membrane without any input of energy by the cell. a. Diffusion b. Osmosis.
The Selectively permeable Cell Membrane Diffusion, osmosis, and active transport.
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)

Thinking Log 19. T/F Diffusion requires the use of energy. 20. T/F Diffusion of water is call osmosis.
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.
Transporting substances By Sangarun sangchachat Diffusion Diffusion is the movement of particles from an area of high concentration to an area of low.
Diffusion The movement of molecules from an area of high concentration to an area of low. concentration.

Take out your homework. Quiz Time!!! 1.What is diffusion? 2.What is osmosis? 3.Use the terms isotonic, hypertonic and hypotonic do describe what is happening.
C ELL T RANSPORT Chapter 5. PASSIVE TRANSPORT Diffusion.
Aim: How can we compare active and passive transport?
Materials move across membranes because of concentration differences.
