Parenchyma pertains to an animal tissue that forms an important part of an organ as against other connective tissues. They are the functional parts of an organ like for instance, the nephron of the kidney or the alveoli of the lungs.
In Botanical parlance, parenchyma is the primary or major tissue of higher plants comprising of thin-walled cells that are able to undergo cell division when mature. The parenchyma is known to form the larger area of leaves, fruit pulp, stem-pith and the roots. In plants also, the major and primary functions like respiration, photosynthesis, manufacture and storage of food, assimilation and excretion are done mainly in the parenchyma cells. The first time the word was used in popular English literature was probably toward the later half of the 19th century.
