MEMBRANE BUBBLES THAT STORE
Vacuoles are membrane-bound sacs inside cells that work like storage vaults. In plant cells, one giant central vacuole can take up most of the cell's interior space. It holds water, sugars, ions, pigments, and even waste products the cell needs to set aside. Animal cells also have vacuoles, but they are usually much smaller and more numerous. Whether huge or tiny, vacuoles keep supplies organized until the cell is ready to use them or send them elsewhere.
⚡ DID YOU KNOW?
The word vacuole comes from the Latin word for "empty space." Early microscopists saw clear bubbles in plant cells and named them before scientists fully understood how packed with water and dissolved materials they really are.
VAULT!
MEMBRANE
🫧 Each vacuole is wrapped in its own membrane
