Cortex : In dicotyledon stem cortex divided into three parts :
(a) Hypodermis (b) General cortex ( c) Endodermis
(a) Hypodermis : It is present just below the epidermis. It provides additional support to
epidermis. It is thick multicellular layer. This layer is composed of collenchyma and their
cells also contain chloroplast.
(b) General Cortex: This part is composed ofparenchyma. Storage of food is the main
functiono f the cortex.Resinc anaVmucilagcea nala re present in it. These are schizogenous
in origin. The innermost layer of the cortex is called endodermis.
(c) Endodermis: It is single celled thick layer. The cells ofendodermis are barrelshaped.
These cells accumulate more starch in stem of dicot. Thus, it is known as "starch sheath".
