Parenchyma cells have primary walls that are relatively thin and flexible, and they usually lack secondary walls. When mature, parenchyma cells usually have a large central vacuole. Parenchyma cells perform most of the metabolic functions of the plant, synthesizing and storing various organic products. Some parenchyma cells have plastids that store starch. The fleshy tissue of most fruits is composed mainly of parenchyma cells.
