What is the main function of the central vacuole in a plant cell?
A
to break down molecules to release energy
B
to store water and other materials
C
to absorb energy from the Sun to produce food
D
to contain the cell’s genetic material
Explanation: 

Detailed explanation-1: -Among its roles in plant cell function, the central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.

Detailed explanation-2: -Vacuoles store nutrients and water on which a cell can rely for its survival. They also store the waste from the cell and prevents the cell from contamination. Hence, it is an important organelle.

Detailed explanation-3: -Vacuole helps in storage of salts, minerals, pigments and proteins within the cell. It isolates metabolic waste that might be harmful to the cell. It maintains turgor pressure. It facilitates endocytosis and exocytosis.

Detailed explanation-4: -The main functions of vacuoles include maintaining cell acidity and turgor pressure, regulating the storage and transport of substances, controlling the transport and localization of key proteins through the endocytic and lysosomal-vacuolar transport pathways, and responding to biotic and abiotic stresses.

Detailed explanation-5: -Central vacuoles are large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell. A fluid-filled central vacuole exerts pressure on the surrounding components of the cell and the cell wall.
