Cell Membrane.
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.
Diffusion The movement of molecules from an area of high concentration to an area of low. concentration.
Cellular Transport Test Review. What does this picture represent??
Aim: How can we compare active and passive transport?
Active vs. Passive Transport FA Learning Goal: Compare and contrast active and passive transport.
Passive vs. Active Transport. Passive Transport Does NOT require energy Moves substances from higher to lower concentration.
What is Osmosis? Osmosis is a form of passive transport (no extra energy needs to be used) where water molecules move down their concentration gradient.
Materials move across membranes because of concentration differences.

Cell Membrane …71

Cell Membrane…page 71 Allows material into and out of the cell Semi permeable (some) Made of a phospholipid bilayer OSMOSIS-brings water into and out of the cell DIFFUSION-brings other materials in/out of the cell (Oxygen, food)

Active transport – the movement of molecules across a cell membrane from an area of low concentration to high concentration Low to high requires energy Passive transport – the movement of molecules from an area of high concentration to low concentration. High – low does not require energy diffusion and osmosis
