vacuoles
Cellular storage bubbles
Vacuoles are membrane-bound compartments within cells that store water, nutrients, or waste products.
In plant cells, a large central vacuole maintains pressure against the cell wall, keeping the plant rigid; when the vacuole loses water, the plant wilts.
Animal cells typically have smaller, more numerous vacuoles.
The vacuole swelled as the cell absorbed water.
