What is the primary role of a vacuole in a cell?

The primary role of a vacuole in a cell is to store materials such as water and nutrients. Vacuoles are membrane-bound sacs found in both plant and animal cells, though they are more prominent in plant cells. In plants, the large central vacuole serves several functions, including maintaining turgor pressure, which helps keep the plant upright and supports its structure. Additionally, vacuoles can store ions, waste products, and other substances that the cell may need to maintain homeostasis or to use later. The storage capacity of vacuoles allows the cell to manage various substances efficiently, making them essential for overall cellular function.
