Characteristics of Fungi
What supergroup are fungi apart of?
Opisthokonta
The thallus (body) of most fungi is called a...
Mycelium
This process occurs when a piece of mycelium breaks off and grows into a new, independent fungus.
Fragmentation
The fusion of haploid hyphae from two different mating types during sexual reproduction called?
Plasmogamy
What phylum produces axsexual zoospores and some exhibit alternation of generation life-cycle?
Blastocladiomycota
Most Fungi are unicellular or multicellular?
Multicellular
The hyphae of the mycelium gives a ______ surface area which ______ absorption
Large, Maximizes
The type of asexual reproduction typical in yeasts where a small outgrowth forms and pinches off from the parent cell.
Budding
Nuclei must fuse
Which phylum includes the simplest fungi which may resemble the first fungi to have evolved?
Chytridomycota
Most fungi are _____ _______ meaning they break down wastes or remains of plants and animals.
Saprotrophic Decomposers
What are porous cross walls that partition hyphae into individual cells?
Septs
Unlike molds, these fungi reproduce asexually by simple cell division and budding, often in moist environments.
Yeasts
What stage occurs when nuclei of each mating type pair off, two to a cell?
Dikaryotic
This fungal group includes species that commonly form black bread mold and produce zygospores.
Zygomycota
Fungi are heterotrophic by ______.
Absorption
Fungal cell walls are composed of?
Chitin
These fungi produce visible mycelia and reproduce asexually by forming haploid spores through mitosis.
Molds
This stage occurs after plasmogamy, but haploid nuclei haven't fused yet.
Heterokaryotic Stage (n + n)
A scientist discovers a fungus living symbiotically in plant roots, increasing phosphorus absorption for the plant. It most likely belongs to this group.
Glomeromycota
Fungal cell secrete ______ ______ that break down then reabsorb resultant nutrient molecules.
Digestive Enzymes
Glycogen
A single-celled fungus living in grape juice reproduces by forming small protrusions that pinch off. This organism is most likely this type of fungus.
What occurs after nuclei fuse and leads to spore formation?
Meiosis
Which phylum lives exclusively in the guts of ruminants and other herbivores?
Neocallimastigomycota
