where is the majority of stomata located in a leaf
Stoma Stomata are present in the sporophyte generation of all land plant groups except liverworts. 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.[4]: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.[5] Leaves with stomata on both the upper and lower leaf 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.[5] Size varies across species, with end-to-end lengths ranging from 10 to 80 µm and width ranging from a few to 50 µm.[6]
Synapsis This is not to be confused with mitosis. Mitosis also has prophase, but does not ordinarily do pairing of two homologous chromosomes.[3]
Is It Fall Yet? The film chronicles the characters' summer break between seasons four and five.
Ascaris lumbricoides Infections with these parasites are more common where sanitation is poor,[10] and raw human feces are used as fertilizer.
