Parenchyma cells have thin cell walls which are rich in pectins and thus stain pink with Toluidine Blue. They also have Simple Pits. You can also observe small Leucoplasts surrounding the Nucleus. (stained with Toluidine Blue). | ||
 |
Simple pits seen on an end wall between two Parenchyma cells. | ||
 |
The Parenchyma cells in some seeds develop thick cell walls which can be metabolized during seed germination. These resemble sclereids and are virtually indistinguishable from them. You need to ask a Botanist to be sure!. Note the extremely long pits in the cell walls. | ||

Storage Parenchyma cell from Pinus cotyledon. The Vacuole (V) is being formed by the metabolism of the storage lipids. N=Nucleus | ||
 |
Later stage in the development of a storage parenchyma cell from Pinus cotyledon. Note the vacuolation. due to the breakdown of storage lipids and proteins (PB = Protein Body). | ||
 |
Immature Parenchyma cell showing two Vacuoles, two Amyloplasts and several dark Spherosomes. Note the thin cell walls. | ||
 |
Electron micrograph of a "typical" Parenchyma cell showing the Nucleus, Chloroplasts & Mitochondria. note the thin cell walls and the intercellular air spaces at the lest side of the cell. | ||
 |
Electron micrograph of a "typical" Parenchyma cell. Note the large central vacuole, the peripheral cytoplasm with well developed chloroplasts and the relatively thin cell wall. | ||
