What is osmosis? |
Osmosis is the net movement of water from an area of high water potential to an area of low water potential through a partially permeable membrane |
|
|
|
What is the water potential of pure water? |
Y0 That means that all other solutions is negative |
What does that mean for other solutions? |
|
|
What happens to an animal cell in pure water? |
The cell has a lower water potential than its surroundings so the water diffuses in causing the cell to burst. |
|
|
|
What happens to an animal cell in a isotonic solution |
There is no change as the water potential is the same in and out of the cell. |
|
|
|
What happens to a animal cell in a concentrated solution? |
The animal cell has a higher water potential than its surroundings so water diffuses out of the cell to its surroundings causing the cell to shrink. |
|
|
|
What happens to a plant cell in a pure water solution? |
The plant cell has a low water potential than its surroundings so water diffuses into the cell causing the vacuole to swell pushing the contents against the cell wall |
|
|
|
What happens to a plant cell in a isotonic solution? |
There is no change as the cell has the same water potential as its surroundings. |
|
|
|
What happens to the plant cell in a concentrated solution? |
The plant cell has a higher water potential and it's surrounding so water diffuses out of the vacuole causing the cell membrane to pull away from the cell wall as the vacuole shrinks. The cell is then plasmolysed |
What is the cell called when this happens? |
