pa·ren·chy·ma

(pə-rĕng′kə-mə)
The basic tissue of plants, consisting of thin-walled, nonspecialized cells that sometimes adapt to specialized functions. The internal layers of leaves, the cortex and pith of the stem, and the soft parts of fruits are made of parenchyma. In higher plants, parenchyma supports the plant body, roots, and leaves; it also stores water and contains chloroplasts in which photosynthesis takes place.
