Final Flashcards
A number of fungi produce conidia during their lifecycle. Conidia are…
Asexual spores
In Fungi the occurrence of plasmogamy but not karyogamy will often result in…
A dikaryotic phase
Which of the following is not a characteristic of fungi and why?
A. Heterotrophic nutrition B. Dikaryotic hyphae C. Multicellularity D. Cellulosic cell wall E. function primarily as decomposes
D. Cellulosic cell wall - fungi have chitinous cell walls
Explain the difference between fungal hyphae and mycelium
Fungal hyphae are the filaments that combined make up the mycelium
Describe how fungi grow and obtain their nutrition
Fungi grow from hyphae that intertwine into the substrate. Digestion is extracellular, meaning they release digestive enzymes into the substrate to break down material and then it is absorbed by the hyphae.
What are the three possible fates for hybrids generated between two closely related species
Reinforcement
Fusion
Stability
Irregularities in meiosis can produce unreduced gametes. Fusion of unreduced gametes within or between two species can produce which two different types of polyploidy

Autopolyploidy
A derived character state
Apomorphic
An ancestral character state
Plesiomorphic
