Parenchyma (Para-beside, enchyma-In poured) Parenchyma is the fundamental tissue of the plant body. It is found in every part of the plant body like pith and cortex of stem and root, mesophyll of leaves, flesh of fruits, floral parts and even in xylem and Phloem. Cells have thin primary walls and polyhedral shapes.
According to Wikipedia, the cortex is the outermost layer of the stem or root of a plant. It transports materials into the central cylinder of the root through diffusion and stores food in the form of starch. The cells inside the cortex may also contain stored carbohydrates or other substances such as resins, latex, essential oils and tannins.
