1. Plasmolysis: The most prominent feature of a wilted plant cell is plasmolysis. This is the process where the cell loses water and shrinks away from the cell wall.
* Mechanism: When the surrounding environment has a higher solute concentration (i.e., is more hypertonic) than the cell's cytoplasm, water moves out of the cell by osmosis. This causes the cell's central vacuole, which is normally filled with water, to shrink, and the cytoplasm pulls away from the cell wall.
2. Reduced turgor pressure: Turgor pressure is the pressure exerted by the cell's contents against the cell wall. In a wilted plant cell, the turgor pressure is significantly reduced due to the loss of water. This causes the cell to become flaccid and the plant to droop.
3. Reduced photosynthetic activity: The loss of water and reduced turgor pressure can affect the plant's ability to photosynthesize effectively.
4. Potential damage: If the wilting is severe and prolonged, it can lead to irreversible damage to the plant cells, ultimately leading to death.
Other features:
* Appearance: Wilted plants look droopy and their leaves may appear limp or curled.
* Touch: The plant may feel dry and brittle to the touch.
Important Note: While the above features describe a wilted plant cell, it's important to note that not all cells in a wilted plant are necessarily plasmolyzed. Some cells may still retain some turgor pressure, but overall, the plant will exhibit a reduced level of turgidity.
