What characterizes a turgid cell?

A turgid cell is characterized by being swollen with water, which occurs when the cell is filled with water and the cell wall pushes against the plasma membrane. This state is important for plant cells because it helps maintain structural support, making the plant firm and upright. The water inside the cell vacuoles creates internal pressure, known as turgor pressure, which is essential for the overall health and function of the plant.

In contrast, a cell lacking water would not be turgid and would actually be flaccid or limp, indicating a lack of turgor pressure. A poorly structured cell does not specifically describe the turgidity or firmness of the cell and could refer to various issues not directly related to water levels. Likewise, a cell that has burst open typically indicates that it has been subjected to too much internal pressure or has lost structural integrity, which is the opposite of being turgid. Therefore, the definition of a turgid cell specifically aligns with the condition of being swollen with water, supporting the overall function of the plant.
