What is the function of vacuoles in a cell?

Vacuoles play a crucial role in the cell by storing a variety of substances, including water, salts, sugars, and other materials. This storage function is significant for maintaining cell rigidity and turgor pressure, especially in plant cells, where the central vacuole can occupy a large portion of the cell's volume. By accumulating water and maintaining cellular pressure, vacuoles help support the cell's structure and overall integrity.

Additionally, vacuoles can serve as a compartment for waste products, contributing to the detoxification of harmful substances and helping in the recycling of cellular components. While they may also have roles in transporting materials and cellular processes, their primary and essential function remains the storage of vital substances necessary for the cell's health and functionality.
