Dicot Leaf vs Monocot Leaf (Difference between Dorsiventral and Isobilateral Leaf) Dicot leaves are also called as dorsiventral leaves because they possess distinct dorsal and ventral sides. Bundle sheath is parenchymatous and in case of large bundles it extends upto the epidermis with the help of thin-walled parenchymatous cells.
