Which helps in maintaining form and structure of cells

Options

A. Wall pressure
B. Turgidity
C. Atmospheric pressure
D. D.P.D

Answer

### Step-by-Step Solution:

1. **Understanding Cell Structure**: The form and structure of a cell are crucial for its functionality. In plant cells, this is largely influenced by the presence of a rigid cell wall.

2. **Defining Turgidity**: Turgidity refers to the state of being swollen or firm due to the presence of water. When a plant cell absorbs water, it fills with water, causing the cell to swell and press against the cell wall.

3. **Role of Turgor Pressure**: Turgor pressure is the pressure exerted by the fluid (usually water) inside the central vacuole against the cell wall. This pressure helps maintain the cell's shape and prevents it from collapsing.

4. **Consequences of Low Turgor Pressure**: If a plant cell loses water, the turgor pressure decreases, leading to a condition called flaccidity, where the cell becomes limp and loses its shape.

5. **Conclusion**: Therefore, turgidity, which is maintained by turgor pressure, is essential for maintaining the form and structure of plant cells.

6. **Final Answer**: The correct answer to the question "Which helps in maintaining form and structure of cells?" is **option B: Turgidity**.
