Which of the following is not a function of vacuole?

A

Storage

B

Providing turgidity and rigidity to the cell

C

Waste excretion

D

Locomotion

Vacuoles are storage bubbles found mostly in plant cells. These are used for storage of food or water. The vacuolar membrane is a single layered and is called as tonoplast. Osmotic pressure and turgidity is maintained by vacuoles. They store toxic metabolic by-products or end products of plant cells. Such vacuoles are thrown out of the cell by exocytosis. Thus, the correct answer is option D.
