Line 1: {{wiktionary\|sessile}} '''Sessility''', or '''sessile''', may refer to: * [[Sessility (motility)]], organisms which are not able to move about ~~'''Sessile''' is a term in [[biology]] with two distinct meanings:~~ * [[Sessility (botany)]], flowers or leaves that grow directly from the stem or peduncle of a plant * [[Sessility (medicine)]], tumors and polyps that lack a stalk ~~== In botany ==~~ * Sessility (in crystallography), [[dislocation]] that is not able to move in the slip plane (as opposed to glissile) In [[botany]], '''sessile''' means "without a [[Plant stem\|stalk]]", as in flowers (pedicel) or leaves ([[petiole (botany)\|petiole]]) that grow directly from the [[Plant stem\|stem]] or [[Peduncle (botany)\|Peduncle]]; however, in [[limnology]], sessile vegetation are any [[organism]]s anchored to the [[benthic]] environment. ~~== In zoology ==~~ In [[zoology]], '''sessile''' [[animal]]s are those which are not able to move about. They are usually permanently attached to a solid [[Wiktionary:substrate\|substrate]] of some kind, such as a [[rock (geology)\|rock]], or the [[Hull (watercraft)\|hull]] of a ship in the case of [[barnacle]]s. [[Coral]]s lay down their own substrate. Sessile animals typically have a [[motile]] phase in their development. [[Sea sponge\|Sponge]]s have a motile [[larval]] stage, which becomes sessile at maturity. In contrast, many [[jellyfish]] develop as sessile [[polyp]]s early in their life cycle. Many sessile animals, including sponges, [[coral]]s, and [[hydra (genus)\|hydra]], are capable of [[asexual reproduction]] ''in situ'' by a process of [[budding]]. ~~'''Clumping''' is a behavior in an animal, usually sessile, in which individuals of a particular species group close to one another for beneficial purposes.~~ ==See also== * [[Sedentism]], in cultural anthropology, the practice of living in one place for a long time * [[Sessile oak]] ~~[[Category:Biology]]~~ ~~[[Category:Locomotion]]~~ {{disambiguation}} ~~[[de:Sessile Tiere]]~~ ~~[[it:Sessilità]]~~ ~~[[simple:Sessile]]~~
