Question

Plant cells become turgid when water enters the vacuole. Is this true?

Answer 1

Yes.

Explanation:

Water diffuses in to the plant cell through osmosis and makes the plant cell turgid. This happens when the plant cell is placed in a hypotonic solution.

NOTE: Turgid means that the cell becomes swollen (or filled with water).

Here is a video which discusses osmosis observed in red onion cells.
