- Water is typically stored in vacuoles, making them a safe storage space.
- Vacuoles occupy a significant 90% of the cell's volume.
- They are bounded by a semi-permeable membrane, allowing for selective passage of substances.
- The concentration of vacuoles in transportation is significantly higher than in the cytoplasm.
