Question

Which out of the following is not a function of vacuole?

• A. Storage
• B. Providing turgidity and rigidity of the cell
• C. Waste excretion
• D. Locomotion

Answer 1

The correct option is D

Locomotion

The correct option is A.

Explanation of the correct option:

1. Vacuoles are solitary membrane-bound cell organelles that are involved in waste excretion, storage, and cell structure maintenance.
2. It does not affect the cell's ability to move.
3. A membrane-bound structure called a vacuole is located in the cytoplasmic matrix of a cell.
4. Tonoplast is the name for the membrane that covers the vacuole.

Explanation of the incorrect option:

Option B:

1. Storage bubbles called vacuoles are most commonly seen in plant cells.
2. These are employed for the storage of food or liquids.

Option C:

1. Tonoplast is the name given to the vacuolar membrane, which has only one layer.
2. Vacuoles keep the osmotic pressure and turgidity in check.

Option D:

1. Vacuole saves harmful metabolic byproducts or plant cell byproducts.
2. Exocytosis causes such vacuoles to leave the cell.

Final answer: Locomotion is not a function of the vacuole.
