what does a vacuole do in a plant cell
Plant cells tend to have one large central vacuole which stores food (sugar and salts in solution) and water. The storage of water helps to support the plant. Absorbing more water makes a vacuole bigger which helps a plant to grow.nimal cell vacuoles are much smaller than their plant cell counterparts and in animal cells their roles are more subservient. They assist in expelling proteins and lipids from the cell. The process is known as exocytosis and the role of the vacuole here is to store the molecules and facilitate their transport.
