VacuolesVacuoles

Plants have one large vacuole Plants have one large vacuole that stores food and nutrients, that stores food and nutrients, increases cell size, and acts like increases cell size, and acts like a lysosome.a lysosome.

A wilting plant has lost much of its A wilting plant has lost much of its water and the vacuoles are water and the vacuoles are shrinking. Cell walls help the cell shrinking. Cell walls help the cell keep its structure. When vacuoles keep its structure. When vacuoles are refilled with water, the plant goes are refilled with water, the plant goes back to its original shape. back to its original shape.
