GENERAL HISTOLOGY

Detailed explanation-1: -Vacuoles can also serve as storage compartments for nutrients and metabolites. For instance, proteins are stored in the vacuoles of seeds, and rubber and opium are metabolites that are stored in plant vacuoles.

Detailed explanation-2: -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-3: -Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.

Detailed explanation-4: -Besides carbohydrates, plant vacuoles store proteins, especially in seeds. Leguminous crops such as lentils, peas and soybeans, as well as cereals such as wheat, rye and barley contain specialised protein storage vacuoles which keep a supply of nitrogen for seed germination.
