Stomata are present in the sporophyte generation of all land plant groups except liverworts. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. Monocotyledons, on the other hand, usually have the same number of stomata on the two epidermes.In plants with floating leaves, stomata may be found only on the upper epidermis and submerged leaves may lack stomata entirely.onocotyledons, on the other hand, usually have the same number of stomata on the two epidermes.
