A vacuole is a membrane-bound organelle found in plant and fungal cells, as well as some protists and animal cells. It typically contains a solution of water, salts, sugars, and other substances, which helps maintain turgor pressure, store nutrients, and manage waste products. In plant cells, the central vacuole plays a crucial role in supporting cell structure and regulating the cell's internal environment. Vacuoles can also contain enzymes and pigments, contributing to various cellular functions.
