In view of the fact that wide diversities exist as regards the nature of the plants, a few common dicotyledons and monocotyledons have been selected for the study of anatomical structures. Food energy. The thickness or cuticle on the both surface is equal. The cuticles will be thicker where the light intensity is greater. Leaves of most dicot plants are dorsiventral (oriented horizontally, with differentiated mesophyll) whereas those of monocots are isobilateral (oriented vertically, mesophyll undifferentiated) as seen in transverse section shows the following features.
