What does "turgid" mean in the context of cells?

In the context of cells, "turgid" refers to a state where a plant cell is swollen or distended due to the uptake of water. This occurs when water enters the cell by osmosis, causing the vacuole to fill and exert pressure against the cell wall. This pressure, known as turgor pressure, maintains the structural integrity and rigidity of the plant cell, allowing it to support the plant's overall structure and prevent wilting.

When plant cells are turgid, they can effectively support leaves and flowers, playing a critical role in plant health and growth. This state is particularly important for non-woody plants, as it helps them maintain upright positions and allows for optimal photosynthesis.

In contrast, a dehydrated or shriveled cell would be described as flaccid, showing a loss of turgor pressure. The other definitions provided do not accurately capture the physiological state of a turgid cell. Therefore, the understanding of turgidity connects directly to the importance of water balance in cells, particularly for plant cells.
