Question

Write a short note on vacuoles.

Answer 1

$\huge\textbf{VACUOLE}$ is a membrane bound space found in cytoplasm. It is bound by a single membrane called tonoplast.

In plant cells vacuole is larger than animal cell. In plant cells it occupies space up to 90%.


$\textbf{Types of vacuoles :-}$

1. Sap vacuoles

2. Contractile vacuole

3. Gas vacuole

4. Food vacuole

$\textbf{Function :-}$

1. Tonoplast facilitate the transport of ions against the concentrate gradients into the vacuoles in plant.

2. They may serve as waste deposit bins.

3. It maintain the tuger of plant cell.

4. It also stores food.

→ It contains; water containing organic and inorganic molecules including enzymes.
