Osmosis 0.0 / 5 ? BiologyCell Structure and MovementIGCSEAQA Created by: elkamoogs xdCreated on: 19-12-15 11:39 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. 6 of 6
