Osmosis

HideShow resource information
Osmosis
The movement of water from an area of high concentration to low concentration across a partially permeable membrane.
1 of 6
Isotonic
Equal concentration of water inside and outside the cell (no net movement).
2 of 6
Hypertonic
Higher concentration of solute OUTSIDE the cell. Water moves OUT of cell.
3 of 6
Hypotonic
Higher concentration of solute INSIDE the cell. Water moves INto cell.
4 of 6
Turgor
In a plant - cytoplasm and vacuole expand because there is lots of water. The cells are bigger and push together, making leaves stick out.
5 of 6
Plasmolysis
When a plant is in a hypertonic solution, lots of water leaves the cells, causing the membrane to separate from the cell wall, so it shrivels.
