Description:
Seta /ˈsiːtə/ (plural: setae /ˈsiːtiː/) is a biological term derived from the Latin word for "bristle". It refers to a number of different bristle- or hair-like structures on living organisms.
In zoology, most "setae" occur in invertebrates.[citation needed]
In mycology, "setae" refer to dark brown, thick-walled, thorn-like cystidia found in corticioid and poroid fungi in the family Hymenochaetaceae. Though mainly microscopic, the setae of some species may be sufficiently prominent to be visible with a hand lens.
In botany, "seta" refers to the stalk supporting the capsule of a moss, hornwort or liverwort, and supplying it with nutrients. The seta is part of the sporophyte and has a short foot embedded in the gametophyte on which it is parasitic. Setae are not present in all mosses, but in some species they may reach 15 to 20 centimeters in height.
Synthetic setae are a class of synthetic adhesives that detach at will, sometimes called resetable adhesives, yet display substantial stickiness. The development of such synthetic materials is a matter of current research.
