Explanation:

Vacuoles full of cell sap provide the much-needed turgidity and rigidity in the plant cells.

The vacuole is a cell organelle that is bound by membranes and consist of water and organic and inorganic matter. When water is absorbed by the plant cell, the vacuoles imbibe it and extends and provide rigidity and eventually helps the plant to become turgid as well. For healthy plants, turgidity and rigidity are essential as these enable the plants to maintain its posture and remain upright.

It has three major functions, such as: • Contribute to the rigidity of the plant by using water to develop hydrostatic pressure. • Store nutrient & non-nutrient chemicals. • Break down of complex molecules.
