Spores, Sexual and Asexual Questions
... Essentially all cells, once separated from the mycelium, have the potential to initiate a new thallus. Therefore, spores are non specialised cells and cells which function to disperse the fungus. Arthrospores are fragments of hyphae. Conidia, sporangiospores and zoospores are specialised cells which reproduce the fungi asexually. The sexual spores ...
