|---|---|---|---|---|---|
| passive transport | substances crossing the cell membrane without any input of energy by the cell
🗑
|
||||
| diffusion | movement of molecules from an area of higher concentration to an area of lower concentration
🗑
|
||||
| concentration gradient | the difference in the concentration of molecules across a distance
🗑
|
||||
| equilibrium | the concentration of molecules is the same throughout the space the molecules occupy
🗑
|
||||
| osmosis | the process where WATER molecules diffuse from an area of higher concentration to an area of lower concentration
🗑
|
||||
| hypotonic | describes a solution whose solute concentration is lower than the solute concentration inside the cell
🗑
|
||||
| hypertonic | describes a solute whose solute concentration is higher than the solute concentration inside the cell
🗑
|
||||
| isotonic | describes a solution whose solute concentration is equal to the solute concentration inside the cell
🗑
|
||||
| contractile vacuole | organelles that remove water
🗑
|
||||
| turgor pressure | the pressure that water molecules exert against the cell wall
🗑
|
||||
| plasmolysis | the process in which the cells shrink away from the cell walls, ad turgor pressure is lost
🗑
|
||||
| cytolysis | the bursting of cells
🗑
|
||||
| facilitated diffusion | the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins
🗑
|
||||
| carrier protein | proteins that assist in the movement of molecules across the cell membrane
🗑
|
||||
| ion channel | a complex of protein molecules in a cell membrane that form a pore 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.
