Vacuole By: Patrick Battista and Jack Davis
Structure • A vacuole is a mass of fluid surrounded by a membrane. • Vacuoles are different in plant and animal cells. • In plant cells, the vacuole is much larger and contains water. • In animal cells, the vacuole contains nutrients. • The organelle has no basic shape or size; its structure varies according to the needs of the cell.
Where It’s Located Plant Cell Animal Cell
Functions • Isolates materials that might be harmful or a threat to the cell • Contains waste products • Contains water in plant cells • Maintains an acidic internal pH • Contains small molecules • Exports unwanted substances from the cell • Allows plants to support structures such as leaves and flowers due to the pressure of the central vacuole • In seeds, stored proteins needed for germination are kept in 'protein bodies', which are modified vacuoles
Cells That Have This Organelle • All plant cells • All fungal cells • Some Protist cells • Animal cells • Bacterial cells
