Parenchyma cells are the biochemistry machines of the plant. They are usually described as the typical plant cell, because they are not very specialized. These cells are commonly found in leaves, roots, and stems, usually having a spherical shape with only primary cell walls and highly functional cytoplasm. Source.
While parenchyma cells do occur within what is commonly termed the xylem the more identifiable cells, tracheids and vessel elements, tend to stain red with Safranin-O. Tracheids are the more primitive of the two cell types, occurring in the earliest vascular plants.Tracheids are long and tapered, with angled end-plates that connect cell to cell. Vessel elements are shorter, much wider, and lack end plates.hile parenchyma cells do occur within what is commonly termed the xylem the more identifiable cells, tracheids and vessel elements, tend to stain red with Safranin-O.
