CHE SIGNIFICA SOREDIUM IN INGLESE
Soredium
Soredia sono strutture riproduttive comuni dei licheni. I licheni riproducono asesualmente impiegando una semplice frammentazione e produzione di soredia e isidia. Soredia sono propaghi polveri composti di iphae fungine avvolte intorno a cianobatteri o alghe verdi. Ipha fungine costituiscono la struttura del corpo base dei licheni. La soredia viene rilasciata attraverso aperture nella corteccia superiore della struttura dei licheni. Dopo la loro liberazione, la soredia si disperde per stabilire i licheni in una nuova posizione.
definizione di soredium nel dizionario inglese
La definizione di soredoum nel dizionario è un organo di riproduzione vegetativa in licheni costituito da un gruppo di cellule algali racchiuse in ife fungine: disperse dal vento, insetti o altri mezzi.

Soredia : A soredium is a small but non-corticated bud-like outgrowth present on
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
