Biodiversity Unit 2 Exam Questions With
Correct Answers
Kingdom Fungi - ✔✔-Decomposers
-heterotrophs (w/ extracellular digestion)
-saprobes
-chitin
Thallus - ✔✔body
Mycelium - ✔✔what the body is made up of
Hyphae - ✔✔thread like, where the nutrience is absorbed
Septate - ✔✔more evolved, many cells divided by walls
Coenocytic - ✔✔one huge cell with many nucleus, more primitive
Haustoria - ✔✔branching projections that push through cell walls into the living plant cells,
absorbing nutrient
Heterokaryon - ✔✔e.g. Dikaryon
Dikaryon - ✔✔temporary stage during sexual reproduction before the fusion of nuclei
Karyogamy - ✔✔fusion of nuclei
N= Ploidy - ✔✔how man chromosomes present
, haploid - ✔✔(n) 1 set
diploid - ✔✔(2n)
dikaryotic - ✔✔(n+n)
spore dispersion - ✔✔easily spread in the wind or water, ensuring that they will be scattered
over distances, & that at least some of them will find conditions suitable for growth
fungal survival - ✔✔when fungus faces dwindling supply, they reproduce spores rapidly and
abundantly, the spores remain dormant until the conditions improve or disperse to other areas
where nutrient supplies are higher
phylum Zygomycota - ✔✔-spores dispersed by air
-hyphae w/ few or not septa (=coenocytic)
-Rhizopus= black bread mold
Phylum Ascomycota - ✔✔SAC FUNGI
-largest class
-free living
-symbiotic
-spores dispersed by air
-septate hyphae w/ perforations
-Ascus/ spore sac forms Ascocarp- reduction structure
Phylum Ascomycota (Representatives) - ✔✔-Peziza
-Saccharomyces/ Yeast
-Claviceps/ Red ergot
-penicillium -> Penicillin
-Morels & Truffles
-Cheese, wine and bread
