CO OZNACZA SŁOWO SOREDIUM
Soredium
Soredia to wspólne struktury rozmnażania porostów. Porosty rozmnażają się bezobjawowo, wykorzystując prostą fragmentację i produkcję soredia i isidia. Soredia to sproszkowane propagandy złożone z grzybiczych hyphae owiniętych wokół cyjanobacteria lub zielonych glonów. Grzybowe hyphae tworzą podstawową strukturę porostów. Soredia jest uwalniana przez otwory w górnej korykcie struktury porostowej. Po ich uwolnieniu soredia rozprowadza się w celu ustalenia porostów w nowym miejscu.

the upper surface of the lichen thallus. It is made up of only a few algal cells,
enclosed by only a few fungal hyphae (Fig. 21.6E). Both isidia and soredia
contain ...
Each soredium forms a new thallus under favourable conditions. According to

scales of different kinds such as hormocysts, phyllidia, blastidia, goniocysts and ...

they are readily rubbed off the thallus and disseminated by wind. Each soredium
on falling over a suitable substratum germinates and grows into a new thallus.
