A cell is kept in water having low water potential. What will happen?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Water Potential:** - Water potential is a measure of the potential energy in water, which determines the direction of water movement. It is influenced by solute concentration and pressure. - Pure water has the highest water potential, which is defined as zero. When solutes are added to water, they bind with water molecules, reducing the concentration of free water molecules and thus lowering the water potential. 2. **Identifying the Conditions:** - In the given scenario, the cell is placed in water with low water potential. This indicates that the solution outside the cell has a higher concentration of solutes compared to the inside of the cell. ...
