Plasmolysis
Plasmolysis is the shrinking of the protoplasm of a cell away from the cell wall due to the loss of water through osmosis. When a plant cell is placed in a hypertonic solution (higher solute concentration outside the cell), water moves out of the cell through osmosis, resulting in the shrinking of the cell. This can lead to wilting of the plant. Plasmolysis is a reversible process, and the cell can regain its shape and size when placed in a hypotonic solution (lower solute concentration outside the cell).
Plant Water Relations
The transfer of water, nutrients, and other materials from one section of the plant to another is referred to as transport in plants. Plants rely on their transport system for growth, survival, and reproduction. Water transport in plants is critical for sustaining the turgor pressure required for cell structure and function.
