BIOL 2260 Fungi and Lichen UPDATED ACTUAL
Questions and CORRECT Answers
Club fungi The Club Fungi, or Basidiomycetes, are one of the
commonly recognized groups of true fungi, and
form a monophyletic group of fungi. This group
includes the mushrooms and toadstools, as well as
shelf fungi, coral fungi, jelly fungi, stink horns, rusts,
smuts, earth stars, and fairy rings. These fungi are
major decomposers of plant leaf litter in moist and
forested systems, especially with their ability to
decompose the lignin in wood. They are found in
practically every terrestrial ecosystem, as well as
freshwater and marine habitats.
Sexual spores Produced by meiosis on basidia
Karyogamy Fusion of 2 haploid nuclei to form a diploid cell
Plasmogamy Fusion of 2 protoplasts
Meiosis Production of haploid cells
Basidia A club shaped spore bearing structure produced
by Basidiomycetes
, Homobasidiomycetes/Homobasidiu basidia are not divided into compartments by walls
m (septae). In these types of basidia karyogamy
(nuclear fusion) & meiosis are completed in a
common space within the basidium such that the
haploid products are in the same container
Heterobasidiomycetes/Heterobasidi karyogamy is accomplished in a common space
um (Phragmobasidium) but as meiosis proceeds walls (septations = septae)
appear along the metaphase plate and the haploid
products occupy separate walled-off portions of
the basidium
Monokaryotic hyphae/Monomitic Hyphae with one nucleus per cell
hyphae
Dikaryotic hyphae/Dimitic hyphae hyphae with two nuclei per cell
True fungi heterotrophic (feeding on others) organisms with
cell walls containing the chemical constituent
chitin. True Fungi include Basidiomycota,
Ascomycota, Zygomycota & Chytridiomycota,
though genetic analysis has resulted in recognition
of many more sub-groups of Fungi
Chitin Heterotrophic (feed on others) organisms with cell
walls contain Chitin. Chitin is a nitrogen which
contains carbohydrates
