Vacuoles
By Hannah Rogers, Emily Urbanovitch, and Elizabeth Wood

2. Central Vacuole: Structure
The prominent organelle in older plant cells
Largest organelle in the cell surrounded by membrane
Solution inside (cell sap) is the plant cell’s main repository of inorganic ions

3. Central Vacuole: Function
Storage
Breakdown of waste products
Hydrolysis of macromolecules
Maintain pressure for support of growing cells

4. Other Information:
Enable plants to grow with minimal investment in new cytoplasm
Develops from the combination of smaller vacuoles

5. Contractile Vacuole: Structure
Enveloped in membrane

6. Contractile Vacuole: Function
Pump excess water out of the cell
In plants:
Some hold reserves of important organic compounds
Protect against herbivores
Contain pigments which attract pollenating insects to petals

7. Other Information: Important in maintaining hydrostatic equilibrium
Found in unicellular organisms

8. Food Vacuole: Structure
Enveloped in membrane
Formed by phagocytosis

9. Food Vacuole: Function
Digestive function
