What is Vacuole ?
its function.

Vacuole is a storage sac like organelle for solid or liquid content.

Its function is to provide rigidity and turgidity. It also stores proteins, food, etc.

That is to say that their function is really to handle waste products, and by handle, mean take in waste products and also get rid of waste products. Sometimes the waste product is water, and therefore a vacuole would have as its function to maintain the balance of water inside and outside a cell. Sometimes a vacuole's function is to get rid of harmful toxins or to clear the extracellular space of those harmful toxins by bringing them into the cell for conversion; for chemical conversion into more safe compounds.
