passive transport
Help!
|
|
||||
|---|---|---|---|---|---|
| Passive Transport | does not require energy
🗑
|
||||
| Diffusion | molecules or ions scatter evenly througout environment
🗑
|
||||
| Concentration gradient | movement of molecules form high concentration to lower concentration
🗑
|
||||
| Simple Diffusion | Nonpolar substances diffuse directly through the lipid bilayer ex. Oxygen, & Carbon dioxide
🗑
|
||||
| Osmosis | movement of water throught selectively permeable membrane
🗑
|
||||
| Toniciy | tone or shape of cells
🗑
|
||||
| isotonic solutions | equal amounts on both sides of membrane cell shape does not change
🗑
|
||||
| Hypertonic Solution | water moves out of cell faster than moves in, cell shrinks:crenation
🗑
|
||||
| Hypotonic Solution | water move in cell faster than it move out, cell swells and may burst
🗑
|
||||
| Lysis | brustin cell
🗑
|
||||
| hemolysis | bursting red blood cell
🗑
|
||||
| Facilitated diffusion | dnt pass thru lipid bilayer: transported substance either binds to protein carriers or moves through water-filled protein channels. no energy required
🗑
|
||||
| Filtration | forces water and solutes through membrane wall by hydrostatic preassure.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
