|---|---|---|---|---|---|
| diffusion | The movement of particles from an area that is more crowded to an area that is less crowded.
🗑
|
||||
| equilibrium | When the system is balanced and there is the same amount of particles inside and outside of the cell.
🗑
|
||||
| osmosis | The movement of water across a selectively permeable membrane.
🗑
|
||||
| selectively permeable membrane | A membrane that allows somethings to pass through it and others can not.
🗑
|
||||
| passive transport | Type of transport in which particles move from an area of high concentration to low concentration and no energy is used
🗑
|
||||
| active transport | Type of transport in which particles move from an area of low concentration to high concentration and lots of energy is used.
🗑
|
||||
| facilitated diffusion | When particles move into or out of the cell through protein channels WITHOUT using energy.
🗑
|
||||
| endocytosis | When the cell membrane wraps around a particle and brings it into the cell.
🗑
|
||||
| exocytosis | When vesicles move materials to the cell membrane and materials are released from the cell.
🗑
|
||||
| hypertonic solution | Solution in which there is a high concentration outside of the cell so water leaves the cell and the CELL SHRINKS
🗑
|
||||
| hypotonic solution | Solution in which there is a low concentration outside of the cell so water enters the cell and the CELL SWELLS
🗑
|
||||
| isotonic solution | Solution in which the concentration is about the same inside and outside of the cell so the cell stays the same.
🗑

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.
