Block C 1 Flashcards
fungal cell biology
most fungi are multicellular forming a network called
hyphae
hyphae that extend above the surface can produce asexual spores called
conidia
conidia are often what
pigmented and resistant to drying
what are the compacted tufts that hyphae called
mycelia
what are most fungal cell walls made of
chitin
what helps plant roots to obtain phosphorus
mycorrhizae
some fungi produce macroscopic reproductive structures called
fruiting bodies
2 examples of fruiting bodies
mushrooms and puffballs
what can mycoses in humans range from
athletes foot to histoplasmosis
how do most fungi reproduce and how many forms
asexual
3 forms
what are the 3 forms that fungi reproduce by
-growth and spread of hyphal filaments
-asexual reproduction of spores
-simple cell division
how do fungi sexual spores originate
fusion of 2 haploid cells to form a diploid cell
(ascospores, basidiospores, zygospores)
what are spores resistant to
drying
heating
freezing
chemicals
what is earliest fungal linage thought to be
chytridomycetes
global amphibian declines- chytrids
where are chytrids found
moist soil and freshwater
what has batrachochytrium been implicated in
massive die off of amphibians
