The vacuole, a storage organelle found within cells and notably large in many plant cells, primarily serves what general function?

ADirectly synthesizing proteins
BStoring water, nutrients, and waste products, while also helping maintain the cell's internal pressure and structural rigidity
CProducing the cell's main energy supply
DProducing the cell's genetic material

Explanation

The vacuole is a storage organelle found within cells, and it’s notably large and prominent in many plant cells, where it primarily serves to store water, various dissolved nutrients, and cellular waste products, while also playing an important role in maintaining internal pressure, called turgor pressure, that helps keep the plant cell, and by extension much of the overall plant structure, appropriately firm and rigid. When a plant does not receive sufficient water, its cells’ vacuoles lose some of this internal pressure, which is part of why an underwatered plant often visibly wilts. Animal cells generally contain much smaller vacuoles, if any are present at all, compared to the typically large, prominent central vacuole commonly found within most mature plant cells.
