Study Notes
Vacuole Function and Contents
- Ca oxalate crystals in the vacuole help to regulate calcium ion concentration in the cell.
Plant Vacuole Contents
- Glucose is mainly accumulated in plant vacuoles, particularly in the storage vacuoles.
- Fructans, a type of polysaccharide, are stored in plant vacuoles and serve as an energy reserve.
Characteristics of Plant Vacuoles
- Lipids are NOT typically found in plant parenchyma vacuoles, unlike in other cell types.
Aquaporin Function
- Aquaporins, a type of transmembrane protein, play a crucial role in the vacuole by facilitating the transport of water and small solutes across the vacuolar membrane.
