The following diagram demonstrates the flow of water when a cell is placed in different aqueous solutions. review the labels at the top of each picture. if a marine plant is placed in a salt water aquarium, predict the flow of water and salt into/out of the plant's cells. a) both the water and the salt will move into the plant cells. the cells will swell. b) because the solution is isotonic, there will be no net movement of either water or salt. c) the salt will move into the cells; the water will move out and the plant cells will undergo plasmolysis. d) because the solution is isotonic, only the salt will move into the plant cells. there will be no net movement of water.
