2. The region of tissue next to the outermost layer of plant stems and roots. The cortex lies between the epidermis (the outermost layer) and the vascular tissue. In roots the cortex transfers water and minerals from the epidermis to the vascular tissue, which distributes them to other parts of the plant. The cortex also stores food manufactured in the leaves.
