What is the main function of vacuoles in a cell?

The main function of vacuoles in a cell is to store waste products as well as other materials. Vacuoles are membrane-bound organelles that can contain a variety of substances, including water, ions, nutrients, and waste. In plant cells, vacuoles often take up a significant volume and help maintain turgor pressure, which is essential for structural support. By storing waste, vacuoles also play a crucial role in keeping the internal environment of the cell balanced and free of harmful substances, allowing the cell to function optimally.

In contrast, the other choices represent different cellular functions. Storing genetic material pertains to the nucleus, which contains DNA. Energy production is associated with organelles like mitochondria, which generate ATP through cellular respiration. Transporting nutrients involves processes facilitated by the cell membrane and various transport proteins, rather than a specific storage organelle.
