When the water potential in the cell is greater than the solution it is in
|
|
|
When the water potential in the cell is lower than the solution it is in
|
|
|
When the water potential is in the cell is the same as the solution it is in
|
Detailed explanation-1: -Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.
Detailed explanation-2: -Complete answer: When the plant cell is kept in a solution which has high water potential, water penetrates into the cell which causes the cytoplasm to develop a pressure against the wall, known as turgor pressure.
Detailed explanation-3: -Will water move into or out of a plant cell if the cell has a higher water potential than the surrounding environment? Water will move out of a plant cell if it has a higher water potential (concentration) than the surrounding environment.
Detailed explanation-4: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Detailed explanation-5: -In a hypertonic solution, the net movement of water will be out of the body and into the solution. A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.
