Transport
1. Transport - Movement of materials through the cell membrane. Cells are bathed in a liquid. This makes it easier for materials such as food, oxygen, and water to move into and out of the cell. Model of the cell membrane
3. Transport - Movement of materials through the cell membrane.

7. Transport - diffusion Diffusion Osmosis Facilitated diffusion Active transport Diffusion is the process by which molecules move from areas of higher concentration to areas of lower concentration.
8. Transport - diffusion Diffusion Osmosis Facilitated diffusion Active transport Molecules move from high to low
9. Transport - diffusion Diffusion Osmosis Facilitated diffusion Active transport door Examples
10. Transport - diffusion Diffusion Osmosis Facilitated diffusion Active transport Examples You spray some perfume and 30 seconds later it can be smelled down the hall
11. Transport - osmosis Diffusion Osmosis Facilitated diffusion Active transport Osmosis is the diffusion of water from areas of high water concentration to areas of low water concentration across a membrane.
12. Transport - osmosis Diffusion Osmosis Facilitated diffusion Active transport
13. osmosis Watch this animation of water molecules moving across a selectively permeable membrane. Water molecules are the small blue shapes, and the solute is the green. The solute is more concentrated on the right side to start with, which causes molecules to move across the membrane toward the left until equilibrium is reached.
14. osmosis A membrane that allows some things through is “selectively permeable”, Certain solutes like salt and sugar are too large to fit through the cell membrane. Water will move in the direction where there is a high concentration of solute (and therefore a lower concentration of water. )
15. The Rule of the Day a No, really. If you sprinkle salt on something, the water appear to be “sucked” from the cells. Actually, the salt lowers the concentration of water, and the water moves from high to low.
16. Transport - osmosis Diffusion Osmosis Facilitated diffusion Active transport Osmosis can cause serious problems for a cell. Because the cytoplasm is filled with salts, sugars, protein, and other molecules, there is usually a net movement of water into a cell surrounded by fresh water. This can cause them to over inflate like a balloon!
17. Transport - osmosis Diffusion Osmosis Facilitated diffusion Active transport An injection of distilled water into the blood stream can often be fatal. Why?

19. Transport – facilitated diffusion Diffusion Osmosis Facilitated diffusion Active transport What is happening at 1, 2, and 3?
20. Transport – active transport Diffusion Osmosis Facilitated diffusion Active transport A cell expends energy to send molecules the wrong way! From areas of low concentration to areas of high concentration.
21. Transport – active transport Diffusion Osmosis Facilitated diffusion Active transport Normally H+ would flow into the cell. ATP (energy) is used to make it flow “backwards”
22. Transport – endocytosis Diffusion Osmosis Facilitated diffusion Active transport Endocytosis : The intake of large particles through the pocketing of the cell membrane and formation of a vacuole Requires Energy
