Aquatic leaves have the underside of their leaves underwater, so water lilies have their stoma on the upper side of the leaves to allow gas exchange. It also prevents water loss from the leaf. The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". The waxy surface also limits the amount of water allowed to escape through the leaf pores or stomata. Totally submerged plants are the true water plants or hydrophytes. The drip tips divert water off the leaf, so that bacteria and fungus does not have a place to grow.
