Which of the following maintains the turgidity of the cell?

Correct option is C

The correct answer is (c) Vacuoles.

Vacuoles play a vital role in maintaining the turgidity of plant cells. Turgidity refers to the state where cells are swollen due to water absorption, providing structural support and maintaining the plant's upright position.

Role of Vacuoles in Turgidity:

1. Storage of Water and Solutes:

   • Vacuoles store water, ions, and other solutes.
   • The pressure exerted by the stored water against the cell wall is known as turgor pressure.

2. Maintaining Osmotic Balance:

   • By regulating the inflow and outflow of water, vacuoles ensure the cell remains turgid.

3. Structural Support:

   • Turgid cells help plants maintain their rigidity, particularly in stems and leaves.

Additional Information:

• Lysosomes:

  • Known as "suicidal bags," lysosomes contain digestive enzymes.
  • They are not involved in maintaining turgidity.

• Plastids:

  • Involved in photosynthesis (e.g., chloroplasts) and storage (chromoplasts and leucoplasts).
  • They do not contribute to turgidity.

• Cell Wall:

  • Provides structural support and protects the cell.
  • However, it is the vacuole that creates the internal pressure (turgor pressure) to maintain turgidity.
