Vacuoles are a prominent feature of plant cells where they have several functions. Recent research has revealed that a plant cell may contain at least two major types of vacuoles, lytic and storage. Lytic refers to item 6. # Plant vacuoles serve as a "cellular trashbag" for all sorts of compounds and ions such as salt, mineral nutrients, heavy metals and organic compounds, that would be toxic if they were in the cytoplasm. # Anthocyanin pigments occur in plant vacuoles. Anthocyanins provide colors other than green for many flowers and fruits. Fruits that get their color from anthocyanins include apple, grape, raspberry, cherry and Indian corn. Anthocyanins also provide the red colors in fall leaves and colors in some variegated leaves, such as coleus, and nongreen leaves, such as red onion, purple cabbage, red cabbage, purpleleaf plum and red Japanese maple. # Plant vacuoles accumulate enough dissolved compounds to give the plant cell a low enough osmotic potential to absorb water via osmosis. # In conjunction with the cell wall, the vacuole functions to provide turgor for plant cells. Turgor is required for the cell enlargement that is essential for growth. # Vacuoles can store protein or carbohydrates. # Vacuoles may contain hydrolytic enzymes and function in degradation.
