Valucles, typically referred to as vacuoles, are membrane-bound organelles found in cells, primarily in plant and fungal cells. They serve various functions, including storage of nutrients, waste products, and other materials, as well as maintaining turgor pressure to support cell structure. In some cases, vacuoles also play a role in the degradation of cellular waste and can help in regulating the cell's internal environment. Their size and function can vary significantly depending on the type of cell and its specific needs.
