What is the main function of a vacuole in plant cells?

The main function of a vacuole in plant cells is the storage of substances. Vacuoles are membrane-bound organelles that can contain a variety of materials including water, nutrients, waste products, and other molecules. In plant cells, the central vacuole plays a crucial role in maintaining turgor pressure, which helps keep the plant cells firm and supports the overall structure of the plant. Additionally, vacuoles can store important compounds that plants need for growth, defense, and other metabolic functions. Understanding this function is essential in recognizing how plant cells manage resources and maintain their health and stability in their environment.
