Druse crystals are also common in Parenchyma. They are also contained within vacuoles. They resemble the medieval mace. | |
 |
When you combine Amyloplasts, crystals and polarized light, amazing images can be obtained. | |
 |
The vacuoles of parenchyma in seeds may contain large lipid deposits. This is an image of cells from a pine cotyledon stained with Sudan Black. Lipids are an excellent storage reserve as they liberate more energy than carbohydrates. | |
 |
These cells have been stained with IKI and Sudan Black. The amyloplasts have stained brown and the lipids have stained black. | |
 |
Cells from the cotyledons of the "Brazilian Oil Tree" are packed with lipids which stain red with Sudan IV. | |
 |
Seed parenchyma may also contain large amounts of proteins. In this case, the Endosperm (en) of Anthurium contains large deposits of protein which have stained blue. The adjacent Cotyledon (c) has large starch (red) deposits in Amyloplasts. | |
