Hint:

Vacuoles play a crucial role in maintaining turgor pressure in plant cells.

Answer 1

The Correct Option is B

Vacuoles are large, membrane-bound organelles found primarily in plant cells.
They store water, ions, excretory substances, and other molecules.
In addition to maintaining turgor pressure (internal hydrostatic pressure), vacuoles play a key role in waste storage and cell elongation.
