1. What happens to the cells as the salt water flows under the coverslip? The cells dehydrate and shrivel up and the chloroplasts move and change color. The cells have a plasmolysis because they have a loss of water.
2. Why does this happen? Because the salt water is dehydrating the cells. It is similar to when people drink salt water. They get thirsty/dehydrated and need water to rehydrate. Also, the cells have a plasmolysis because they have a loss of water. But when you add back the water, it has an osmosis by giving back they hydration the plant needs.
3. Why didn't the outer boundary of the cell collapse? Because the cell wall is doing its job by not letting the salt water into the cell.
4. Why do plants wilt when there is not enough water? Because they are dehydrated and need water to stay alive. The cells have a plasmolysis because they have a loss of water.
