Stomata are present in the sporophyte generation of the vast majority of land plants, with the exception of liverworts, as well as some mosses and hornworts. In vascular plants the number, size and distribution of stomata varies widely. Dicotyledons usually have more stomata on the lower surface of the leaves than the upper surface. Monocotyledons such as onion, oat and maize may have about the same number of stomata on both leaf surfaces.[2]: 5  In plants with floating leaves, stomata may be found only on the upper epidermis and submerged leaves may lack stomata entirely. Most tree species have stomata only on the lower leaf surface.[3] Leaves with stomata on both the upper and lower leaf surfaces are called amphistomatous leaves; leaves with stomata only on the lower surface are hypostomatous, and leaves with stomata only on the upper surface are epistomatous or hyperstomatous.[3] Size varies across species, with end-to-end lengths ranging from 10 to 80 μm and width ranging from a few to 50 μm.[4]

The stomata in plants' leaves open and close depending on external and internal conditions. Which of the following would most likely cause the stomata to close?A.The plant is taking in too much water from the soil.B.The plant needs additional carbon dioxide for photosynthesis.C.The plant is losing too much water from transpiration.D.The plant needs additional sunlight for photosynthesis.
