|---|---|---|---|---|---|
| diffusion | movement of dissolved molecules in a fluid or gas from a region of higher concentration to an area of lower concentration
🗑
|
||||
| facilitated diffusion | diffusion of molecules assisted by protein channels that pierce a cell membrane
🗑
|
||||
| osmosis | diffusion of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration
🗑
|
||||
| active transport | energy requiring movements of molecules across a membrane from a region of lower concentration to an region of higher concentration
🗑
|
||||
| endocytosis | the process of taking liquids or fairly large molecules in a cell by engulfing them in a membrane
🗑
|
||||
| exocytosis | the opposite of endocytosis; is the release of substances out of a cell by the fusion of a vesicle with the membrane
🗑
|
||||
| selective permeability | condition or quality of allowing some, but not all, materials to cross the barrier or membrane
🗑
|
||||
| hypertonic solution | solution that has a higher concentration of dissolved particles than a cell
🗑
|
||||
| hypotonic solution | solution that has a lower concentration of dissolved particles than a cell
🗑
|
||||
| isotonic solution | solution that has an equal concentration of dissolved particles compared with another solution
🗑

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.
