|
Osmosis |
-The diffusion of water across selectively permeable membrane -The movement of water. -Low solute concentration to area of high solute concentration -Passive (no energy) |
|
|
Diffusion |
-Movement of molecules from an area of high solute concentration to an area of low solute concentration. -Un-facilitated (no help) and is passive -Will occur until equilibrium is reached. |
|
|
Isotonic |
-A solution that causes no change in the size of cell -Both solutions have same concentration of solute. |
|
|
Hypotonic |
-A solution that causes a cell to swell because of osmosis -Lower concentration than another |
|
|
Hypertonic |
-A solution that causes a cell to shrink because of osmosis -Higher concentration than another |
|
|
Fact |
Animal cell will explode in a hypotonic solution but it won't in a plant cell because of the cell wall.
|
|
|
Fact |
Facilitated diffusion occurs through channels in the membrane . It is for molecules that cannot pass through the membrane quickly. |
|
|
Active Transport |
Low concentration to high concentration, requires energy (ATP) |
