Answer 2

Vacuoles are fluid-filled spaces enclosed by a membrane. They store excess water, useful minerals, pigments, and many other substances. Large vacoules are present in plant cells, where they maintain the shape of the plant cell. Smaller and more numerous vacoules are present in animal cells.
