|
|
||||
|---|---|---|---|---|---|
| equilibrium | no net gain or loss of water in this environment
🗑
|
||||
| diffusion | the gradual random spreading of molecules from an area of higher concentration to an area of lower concentration
🗑
|
||||
| pinocytosis | bulk flow of large solutes dissolved in a solution across the membrane into a cell
🗑
|
||||
| osmosis | the diffusion of water molecules only
🗑
|
||||
| hypertonic | a cell environment that has a higher solute concentration and lower water concentration than the cell
🗑
|
||||
| facilitated diffusion | movement of large solutes into or out of a cell through a protein with no energy needed
🗑
|
||||
| exocytosis | secretion of large molecules out of the cell using transport vesicles
🗑
|
||||
| phagocytosis | bulk flow of large solid particles or cells across the membrane into the cell; engulfing material
🗑
|
||||
| hypotonic | a cell environment that has lower solute concentration and higher water concentration that the cell
🗑
|
||||
| active transport | the movement of molecules through a membrane with the use of ATP
🗑
|
||||
| transport protein | integral proteins that solutes pass through when crossing a selectively permeable membrane
🗑
|
||||
| concentration gradient | the direction of flow (net movement) of solutes by diffusion
🗑
|
||||
| passive transport | transport of molecules that requires no energy
🗑
|
||||
| sea water the Great Salt Lake, the Dead Sea | hypertonic environments
🗑
|
||||
| tap water; fresh water lakes, rivers, and streams; distilled water | hypotonic environments
🗑
|
||||
| isotonic | a cell environment that has an equal solute and water concentration with the cells
🗑
|
||||
| IVs, contact wetting solutions, tissue baths | isotonic environments
🗑
|
||||
| crenate | the shrinking of animal cells when exposed to a hypertonic environment
🗑
|
||||
| lyse | the rupturing of an animal cell when exposed to a hypotonic environment
🗑
|
||||
| turgid | the swelling of a plant cell when exposed to a hypotonic environment; plant tissue is rigid and firm due to water pressure within the central vacuole
🗑
|
||||
| plasmolysis | the loss of turgor pressure in a plant cell exposed to a hypertonic environment; tissue is flimsy and flexible due to loss of turgor pressure in plant cells
🗑
|
||||
| turgor pressure | internal pressure in cells created by the absorption of water by osmosis
🗑

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.
