Parenchyma cells are the most common type of cell in most plants. These non-specialized plant cells can divide and specialize into different plant cells under certain environments. This is especially helpful when the plant needs to repair a damaged or broken organ. Photosynthesis, aerobic respiration, and most other metabolic processes take place in these cells. One of their most important functions is to store food and water in their storage vesicles. Parenchyma cells have a surrounding thin primary cell wall.
Parenchyma cells are found in many locations in the plant. For example, the dermal (or “skin”) of a plant consists primarily of parenchyma cells. Parenchyma cells are also found in vascular and ground tissues, although they are not as preeminent in these tissues as they are in the dermal of plants.
