What is the main role of vacuoles in cells?

Vacuoles are membrane-bound organelles primarily responsible for storing and transporting materials within the cell. They can contain a variety of substances, including nutrients, waste products, and other molecules necessary for the cell's survival and function. In plant cells, large central vacuoles also play a critical role in maintaining turgor pressure, which helps keep the plant structure firm. This storage ability is vital for cellular metabolism and overall homeostasis, facilitating the necessary transport of materials throughout the cell and between cells, thus supporting various cellular functions. The function of vacuoles in this context enhances cellular organization and efficiency, allowing for the proper management of resources.
