The difference between Dicot Stem Anatomy and Monocot Stem Anatomy are dicot stem the epidermal multicellular stem hairs are present whereas in monocot stem usually stem hair are absent.
The difference between Dicot Stem and Dicot Root are :- in the former the outermost layer is called epidermis; the outer wall is covered with thick cuticle. The epidermis contains multicellular hairs and stomata here and there whereas in the later the outermost layer is called epiblema. It consists of thin-walled cells and containing intercellular hairs. Stomata and cuticle are absent.
The difference between Vascular Bundles in Monocot and Dicot Stem are in Dicot Stem vascular bundles are arranged in ring whereas in Monocot stem vascular bundles are scattered in ground tissues.
