What is the role of vacuoles in a cell?

To provide structural support
To transport materials within the cell
To store genetic information
To produce energy

The correct answer is: To transport materials within the cell

Vacuoles primarily serve as storage compartments within a cell, holding various substances such as nutrients, waste products, and other materials. They maintain the internal balance of a cell by regulating the concentration of solutes and the pressure of the cytoplasm. This storage capability is essential for the cell's metabolic processes and helps ensure that it has the necessary components available for various functions. While options related to structural support, storing genetic information, or producing energy do have their respective cellular components (such as the cytoskeleton for support, nucleus for genetic information, and mitochondria for energy production), these functions are not the primary role of vacuoles. Vacuoles are not directly involved in the energy production chain, nor do they play a key role in genetic information storage. Their main function is focused on the storage and transport of substances within the cell.
