Definition of the Cortex. Let's explore the cortex layer in more detail. The cortex is defined as root and stem tissue found between the epidermis and vascular tissue of a plant. When you eat potatoes or carrots you are actually eating the root of a plant's cortex.
The primary root tissue is responsible for storing food, which is one of the products of photosynthesis. This layer is sometimes called the cortex. This layer is found after the epidermis and often makes up the bulk of the root. This is especially the case in some plants, such as carrots or radishes.uch like in the plant stem, the vascular cylinder in the root contains xylem and phloem. Xylem moves water and dissolved minerals within a plant, while phloem moves food throughout a plant. The xylem generally moves water up from the roots, while the phloem moves food from the leaves to the roots.
