Vacuole

A vacuole is a membrane-bound organelle (mini organ) that is present in all plant and animal cells, as well as most bacteria. The vacuole regulates the fluid content of the cell and can also be used to help the cell gather food or reproduce. The vacuole can also eject unneeded waste from the cell, isolate anything that can harm the cell, and even allow plants to support such structures as leaves and flowers.
