|---|---|
| What happens if an animal cell is in a solution that is the same concentration as its cytoplasm? | Water will move in and out through its cell membrane at the same rate. The volume of the cell will remain the same. To prevent this happening sea water has the same concentration as the cytoplasm of many animals that live in the sea. |
| What happens if an animal cell is in a less concentrated external solution? | If an animal cell is in a solution that is less concentrated than the cell, water will move into the cell as a result of Osmosis. The cell will enlarge and may burst and die, because they don’t have a cell wall |
| What do you think would happen to an animal cell in a less concentrated solution? | It would burst as it would gain water. |
| What happens If an animal cell is in a more concentrated external solution? | Animal cell in a concentrated solution flower water concentration, it will lose water due to osmosis. Example, Red bloods cells in a high salt blood concentration. Animal cell will shrivel and maybe die. |
| State one location where osmosis occurs in humans? | Water moving from the large intestine into the blood |
