notes
Vacuoles:
- Vacuoles are storage sacs for solid or liquid contents.
- The central vacuole of some plant cells may occupy 50-90% of the cell volume.
- Vacuoles are full of cell sap and provide turgidity and rigidity to the plant cell.
- Amino acids, sugars, various organic acids, and some proteins are stored in it.
- They are also present in the unicellular organisms. Eg. Food vacuoles in amoeba.
