What is the meaning of vacuole?

Vacuole. It is an essential way to isolate materials that may be harmful to the cell. In plant cells wherein vacuoles are relatively large, the vacuole maintains an internal hydrostatic pressure inside the cell and thereby helps plants by providing support to plant structures such as leaves and flowers.
