Loyola Biology 111 Fungi
an organism that feeds on or nourishes from decaying organic matter
consists of a diploid zygote surrounded by a thick protective wall, which forms during sexual reproduction
the black mold on bread
what cell division process produces spores during asexual reproduction?
what fungal cell walls are made up of
a mass of hyphae
each branching filament that makes up the mycelium of a fungus
mutualistic symbiotic association
some benefit to both the fungus and the host
an organism that lives on another and benefits by deriving nutrients at the hosts expense
the tips of the hyphae swell to form ______
when the cytoplasm of the two gametangia merges to form a zygosporangium
the resulting zygosporangium contains many separate haploid nuclei and is termed _____________
the fusion of pairs of nuclei will occur resulting in many diploid cells.
the first structure to emerge from a zygosporangium is a specialized hyphal strand called _________ bearing a sporangium
in the majority of sac fungi, asexual reproduction occurs at the end of specialized hyphae called _________-.
spores can disperse and germinate into new hyphae
what is an advantage of a sporangiophore that grows upwards?
the cytoplasm of two haploid mating hyphae strands fuses, but the haploid nuclei remain separate (plasmogamy). The result is a ________ (two nucleotide) reproductive hypha.
the fruiting family, or _________, forms a form of an intertwined collection of both dikaryotic and haploid hypha
the dikaryotic hyphae ultimately produce sexual spores within structures called ____________.
this group is distinguished by sexual spores that develop on projections from microscopic cells called _________
enmesh around the outer cortex of the root and generally belong to either the Basidiomycota or Ascomycota
lichens live with green algae, so they need to live alongside algae
Why are lichens often the first organisms to colonize bare, rocky areas?
have flat, encrusting bodies
have leafy bodies
appear like mini branching shrubs
