What is the term for a plant cell that is less rigid and has shrunk due to loss of water?

The term for a plant cell that is less rigid and has shrunk due to the loss of water is "plasmolyzed." When a plant cell loses water, typically through osmosis, the central vacuole shrinks, causing the cytoplasm to pull away from the cell wall. This results in a loss of turgor pressure, which is responsible for the rigidity of plant cells.

As the cell becomes plasmolyzed, it appears flaccid and lacks the firmness that is characteristic of a turgid cell, which is a healthy state when the vacuole is full of water. The other options do not accurately describe the state of the cell in this scenario; for example, flaccid cells refer to those that are not under optimal pressure but are not necessarily shrunken, while opaque refers to the clarity of the cell and is not related to its water content or rigidity.
