Characteristics of a fungus
Definition
eukaryotic, multicellular, some unicellular yeast, most are terrestrial, some aquatic, chitinous cell walls, and absorptive heterotroph
Term
Nutrition of a fungus
Definition
secrete hydrolytic enzymes that break down larger molecules to smaller molecules so that they can be absorbed
Term

Definition
nonliving material (fallen logs, animal corpses, animal waste)
Term
parasitic fungi
Definition
feed off cells of a living host
ex: ring worm
Term

Definition
lichen- green algae and a fungus
Term
hyphae
Definition
tiny filaments (composed of tubular walls surrounding plasma membrane and cytoplasm) that make up the body of a fungus
Term
mycelium
Definition
an interwoven mass of hyphae (feeding network of a fungus)
Term
mycorrhizae
Definition
relationship between a fungus and plant roots
Term
process of mycorrhizae
Definition
-fungi deliver phosphate ions & other materials to plant
-plants supply fungi with organic nutrients
Term
Reproduction of fungi
Definition
fungi reproduce by releasing spores that are produced asexually or sexually
Term
Asexual Reproduction of a Fungi
Definition
-hyphae make spore producing structures
-make spores
-germinate (n)
Term
Sexual Reproduction of a Fungi
Definition
-mycelium begin to grow (+,-)
-plasmogomy (cytoplasm from 2 strands fuse)
-heterokaryotic stage (unfused nuclei from different parents)
-Karyogamy (fusion of the two nuclei form a zygote)
-Zygote goes through meiosis->spores->germinate
Term
Phylum Chytridiomycota
Definition
-most are aquatic
-some are decomposers; many are decomposers of plants, protist, and aquatic animals
-form flagellated spores
-contribute to amphibian decline

-terrestrial
-some from mycorrhizae
-ex: Rhizopus (black bread mold) & Pilobolus
Term
Phylum Ascomycota
Definition
-(sac fungi)
-more than 60,000 species
-wide range in size & complexity
-marine, fresh water, & terrestrial found
-decompose plants
-some form mycorrhizae
(ex: morels, truffles, Aspergillus)
Term
Phylum Basidiomycota
Definition
-25,000 species
-decomposers of plant material
-some form mycorrhizae
-some are parasitic
-asexual reproduction is uncommon
ex: mushrooms, shelf bracket fungus, puffballs, smuts, and rusts)
Term

Definition
-sexual reproduction organs have not been found
-ex: Penicillium
Term
Mold
Definition
common name for rapidly growing asexual fungus
Term
Yeast
Definition
unicellular aso or basidiomycete
