Osmosis
Osmisis
| Question | Answer |
|---|---|
| What is a hypertonic solution? | High concentration of solute relative to another solution |
| What happens to a cell in a hypertonic solution? | Water flows out of the cell, the cell shrivels |
| What is a hypotonic solution? | Low concentration of solute relative to another solution |
| What happens to a cell in a hypotonic solution? | Water flows into the cell causing it to swell and may burst |
| What is an isotonic solution? | Equal concentration of solute relative to another solution |
| What happens to a cell in an isotonic solution? | Water flows in an out of the cell at the same rate there is no net movement of water |
| What is the definition of osmosis? | The net movement of water from a region of high water potential to a region of lower water potential through a partially permable membrane |
| What happens to a plant cell in a hypertonic solution? | The vacuole shrivels and becomes flacid/plasmolysed |
| What does plasmolysed mean? | The plasma membrane pulls away from the cell wall |
| What happens to a plant cell in a hypotonic membrane? | The vacuole swells and becomes turgid |
| What happens to an animal cell in a hypotonic solution? | Haemolysis |
| Wat happens to an animal cell in a hypertonic solution? | Crenation |
| What is the name for when an animal cell is placed in a solution of lower water potential, causing the cytoplasm to lose water | Crenation |
| What is the name of the pressure against the cell wall caused by the swelling of the cell? | Turgor |
