Biology - Vacuoles
Vacuoles are compartments within cells that store water, mineral ions or
pigments that give the cell its colour.
If present in animal cells, vacuoles are small and temporary. Plant cells
have a large permanent central vacuole that may occupy in excess of 80% of
the cell's volume. The size of the vacuole may get bigger as the cell
matures and as it collects and stores more substances.
