The structure that imparts turgidity and rigidity to the cell is ______

Options

A. vacuole
B. ribosome
C. cell wall
D. cell membrane

Answer

**Step-by-Step Solution:**

1. **Understanding Cell Structure**: The question asks about the structure that provides turgidity and rigidity to the cell. Turgidity refers to the state of being swollen or firm, which is crucial for maintaining the shape of the cell.

2. **Identifying Key Organelles**: In plant cells, the main structure responsible for turgidity is the vacuole. Vacuoles are large, fluid-filled organelles that help maintain pressure against the cell wall.

3. **Role of Vacuoles**: Vacuoles store water and other substances, and when they are filled with water, they create internal pressure (turgor pressure) against the cell wall. This pressure helps keep the cell firm and prevents it from collapsing.

4. **Comparison with Other Structures**: While other structures like the cell wall and cell membrane also contribute to the overall structure and protection of the cell, the vacuole is specifically responsible for turgidity. The cell wall provides rigidity but does not directly contribute to turgidity in the same way that vacuoles do.

5. **Conclusion**: Therefore, the structure that imparts turgidity and rigidity to the cell is the **vacuole**.

**Final Answer**: The structure that imparts turgidity and rigidity to the cell is **vacuole**.
