Exempel på hur man kan använda STOMATAL i en mening

• The pore is bordered by a pair of specialized parenchyma cells known as guard cells that regulate the size of the stomatal opening.
• Subfamily Pinoideae (Pinus): cones are biennial, rarely triennial, with each year's scale-growth distinct, forming an umbo on each scale, the cone scale base is broad, concealing the seeds fully from abaxial (below the phloem vessels) view, the seed is without resin vesicles, the seed wing holds the seed in a pair of claws, leaves have primary stomatal bands adaxial (above the xylem) or equally on both surfaces.
• The foliage sprays are green above and green marked with whitish stomatal bands below; they emit a strong aroma reminiscent of pineapple when crushed.
• The upper surface ('adaxial' - facing toward the stem of the plant) is conspicuously whitened by narrow stomatal lines.
• 12–14 mm long, quadrangular in cross-section, and dark green on all four sides with inconspicuous stomatal lines.
• The leaves are in decussate whorls of three, 3–6 mm long (to 8 mm long on seedlings) and 2 mm broad, marked with two white stomatal lines.
• The leaves are glaucous green on the upper side of the shoots, and conspicuously marked with bright white stomatal patches on the underside.
• ABA then translocates to the leaves, where it rapidly alters the osmotic potential of stomatal guard cells, causing them to shrink and stomata to close.
• The stomata are usually restricted to the abaxial or underside of the leaf, forming two stomatal bands around the midrib.
• Cunninghamia bears softly spined, leathery, stiff, green to blue-green needle-like leaves that spiral around the stem with an upward arch; they are 2–7cm long and 3–5mm broad at the base, and bear two white or greenish white stomatal bands underneath and sometimes also above.
• 5–3 cm long, 2 mm broad, fairly hard with a prickly spine tip, dark green above, and with two glaucous blue-white stomatal bands below.
• bicolor, noting the very different stomatal placing on the leaves; it also differs in needle number, with 3–4 per fascicle, rather than 2–3; in the cones having thinner scales; and in having a denser, more rounded crown.
• The bottom of the leaf is glaucous with two broad and clearly visible stomatal bands, while the top is a shiny green to yellow-green in color.
• The leaves are evergreen, needle-like, 2–3 cm long and 3 mm broad, with a sharply spined tip and two whitish stomatal bands on the underside; they are spirally arranged, but twisted at the base to lie horizontally either side of the stem.
• The leaves are lanceolate, flat, 8–12 cm long (up to 17 cm on young plants) and 4 mm broad, dark green above, with two paler green stomatal bands below; they are arranged spirally on the stem.
• The taxonomy of Cephalotaxus is difficult, because the species have been defined using characteristics that intergrade with each other, such as the length and shape of needles, bark, and stomatal band color.
• The stomatal pores are largest when water is freely available and the guard cells become turgid, and closed when water availability is critically low and the guard cells become flaccid.
• The leaves are needle-like, 1–2 cm long, rhombic in cross-section, shiny green to grayish-green with inconspicuous stomatal lines; the leaves subtending a bud are distinctively angled out at a greater angle than the rest of the leaves (a character shared by only two or three other spruces).
• Because of these conditions, the flora thriving in the campo rupestre has developed several adaptations, such as carnivory, C4 metabolism, superficial root systems (to absorb periodic rain water faster), underground storage, stomatal crypts, etc.
• Some of these interactions include stomatal conductance, carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose, glycine, and proline), ROS-scavenging enzymes.
