Question

What is the significance of vacuole in a plant cell?

Answer 1

Significance of vacuole in a plant cell :

Vacuoles are large fluid-filled membrane-bound structures present in the cytoplasm of a cell, prominent in a plant cell.

Tonoplasts have special ion pumps and transporters that facilitate uphill transport of many ions and other materials, making their concentration higher in vacuole as compared to the cytoplasm


Vacuole has many functional significance.

Turgor pressure

Vacuoles maintain the turgor pressure of plant cells and help in structural support.

Growth of plant

Vacuoles help in cell growth by absorbing water, exerting turgor pressure on the cell wall and causing the cells to elongate.

Storage

Vacuoles provide an aqueous medium for storage of water soluble substances like sugar, minerals and pigments.

Waste bin

Vacuoles serve as waste deposit bins for unwanted materials like toxins.
