Stoma

... In botany , a stoma (also stomate ; plural stomata ) is a tiny opening or pore , found mostly on ... pumps. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. ... is directly illuminated. Less number of stomata on the upper epidermis can then prevent water ...

Osmoregulation

... modifications to reduce water loss, such as needle-shaped leaves, sunken stomata and thick, waxy cuticles as in the pine. The sand-dune marran grass has rolled leaves with stomata on the inner surface. Osmoregulation in protoctists and animals ...

Photorespiration

... rubisco favors carbon , it can also use oxygen , producing glycolate . This usually occurs when oxygen levels are high; for example, when the stomata (tiny pores on the underside of the leaf ) are closed to prevent water loss. The reaction is: RuBP + rubisco + O 2 → phosphoglycolate ...
