Definition of stomataCategorized under "General"
Definition as written by talinum:
Pore openings in the epidermal layer of plant tissue where transpiration occurs.
Definition as written by Monocromatico:
Structure characterized by a pair of guard cells that inflate in certain circunstances (often in high humidity and low temperature conditions, and in some succulent plants, only at night), opening a space between them through which the plant transpirates.
Stomata are more often found on the lower page of leaves, but in some circunstances (specially in aquatic species), they may be found on both pages. Leafless plants, like cacti, have stomata all over the stem.
Stomata are also organized in different ways, and the organization pattern is a useful taxonomic information.
