  1. What are the hyphae and
    the mycelium of pluricellular
    fungi?

made of contiguous uni ormultinucleated cells) and the mycelium (^)
(a set of hyphae).



  1. What are the types of
    reproduction that occur in
    fungi?
    In fungi there are asexual and sexual
    reproduction.by fragmentation, Fungi reproduce asexually gemmation and
    sporulation. Some species can
    reproduce sexfrom different individuals, even withually by fusion of hyphae
    metagenesis (alternation of
    generations).

    superior portion of the peduncle of some


fungi. These structures contain threproductive cells of the individual. Te (^) hey
