Collenchyma is a specialized plant tissue with thickened primary cell walls. It combines high strength in tension with the ability to grow in length.

Keywords: cell wall; tissue tension; cellulose; pectin

Location and types of collenchyma. (a) Peripheral location in celery petiole; central location in Mimosa pulvinus. (b) Cell‐wall thickenings on tangential walls only (lamellar collenchyma); at cell corners (angular collenchyma) and bordering intercellular spaces (lacunar collenchyma).
