A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol. A vacuole that is maintained at an acidic pH and which contains degradative enzymes, including a wide variety of acid hydrolases. A closed structure that is completely surrounded by a unit membrane, contains liquid, and retains the same shape regardless of cell cycle phase. An example of this structure is found in Arabidopsis thaliana. A lytic vacuole that is maintained at acidic pH and has different tonoplast composition compared to the central vacuole. Found during leaf senescence and develops in the peripheral cytoplasm of cells that contain chloroplast.
