Question | Answer |
Osmosis | movement of water molecules accross a semi-permeable membrane from a region of highwater concentration to a region of low water concentration. |
Solvent | liquid the dissolved other substance |
Solute | substance that has been dissolved |
Solution | mixture of the solvent and solute in a solution |
animal cell is in solution that is the same concentration as its cytoplasm | water will move in and out through its cell membrane at the same rate |
Animal cell is in a solution that is less concentrated than the cell | gain water due to osmosis |
animal cell is in a solution that is more concentrated than the cell | lose water due to osmosis |
Amoeba | single-celled organism that lives in freshwater pools and ponds |
osmoregulation system in amoeba | Contractile Vacuole |
plant cell has a higher concentration of solutes than its surroundings | water moves into the cytoplasm and vacuole |
Turgor Pressure | pressure in the cytoplasm and vacuole against the cell wall of a plant |
cytoplasm of a plant cell has a lower concentration of solutes than the surrounding | water moves out of the cell |
Plasmolysis | loss of water from the cytoplasm and the movement of the cell membrane away from the cell wall |
