|---|---|---|---|---|---|
| passive transport | the movement of substances across a cell membrane without the use of energy by the cell
🗑
|
||||
| diffusion | the movement of particles from regions of higher density to regions of lower density
🗑
|
||||
| concentration gradient | a difference in the concentration of a substance across a distance
🗑
|
||||
| equilibrium | in biology, a state that exists when the concentration of a substance is the same throughout a space
🗑
|
||||
| osmosis | the diffusion of water or another solvent from a more dilute solution (of a solute) to be a more concentrated solution (of the solute) through a membrane that is permeable to the solvent
🗑
|
||||
| hypotonic | describes a solution whose solute concentration is lower then the solute concentration inside a cell
🗑
|
||||
| hypertonic | describes a solution whose solute concentration is higher than the solute concentration inside a cell
🗑
|
||||
| isotonic | when the concentration of solutes outside and inside the cell are equal, the outside solution is said to be isotonic to the cytosol.
🗑
|
||||
| contractile vacuole | in protozoans, an organelle that accumulates water and then releases it periodically to maintain pressure
🗑
|
||||
| turgor pressure | the pressure that is exerted on the inside of cell walls and that is caused by the movement of water into the cell
🗑
|
||||
| plasmolysis | the contraction or shrinking of the cell membrane of a plant cell in a hypertonic solution in response to the loss of water by osmosis
🗑
|
||||
| cytolysis | the bursting of a cell
🗑
|
||||
| facilitated diffusion | the transportation of substances through a cell membrane along a concentration gradient with the aid of carrier proteins
🗑
|
||||
| carrier protein | a protein that transports substances across a cell membrane
🗑
|
||||
| ion channel | a pore in a cell membrane through which ions can pass
🗑

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.
