Definition of parenchyma 1: the essential and distinctive tissue of an organ or an abnormal growth as distinguished from its supportive framework 2: a tissue of higher plants that consists of thin-walled living photosynthetic or storage cells capable of division even when mature and that makes up much of the substance of leaves and roots, the pulp of fruits, and parts of stems and supporting structures
1 Parenchyma tissues are made of simple, thin-walled cells. 2  In a carrot, for example, the parenchyma cells become a storage unit called the cortex. 3  In leaves, a layer of parenchyma tissues under the epidermis is active in photosynthesis.n reviewing plant physiology, plant cells are grouped into tissues based on similar characteristics, then into five distinct structures (organs). 1  Cells â individual building blocks for life processes and growth.
