Fungi overview Flashcards
are fungi eukaryotes or prokaryotes?
eukaryotes
how do fungi ingest their food?
secrete digestive enzymes into food source and reabsorb the nutrients
are fungi saprophytic or parasitic?
can be either
fungi are chemoheterotrophs. what does this mean?
they require organic matter for nutrition
non-photosynthetic
are fungi aerobic or anaerobic?
most are aerobic
how do yeasts grow and reproduce?
typically asexually by budding
sometimes by binary fission and can reproduce sexually
what fungi are unicellular?
yeasts
what fungi are multicellular?
filamentous mould
what are hyphae?
fungal filaments
what do a mass of hyphae collectively make up?
mycelium
what are the two types hyphae?
septate
non-septate
what is the structure of hyphae?
essentially a tube
rigid wall
contain septa
protoplasm tapered at the tip where growth occurs
plasma membrane is closely associated with the walls
what is an apical vesicular cluster and what is its role?
an accumulation of membrane-bound vesicles at the extreme tip
plays a role in apical growth
what is the cell wall of the hyphae composed of?
chitin and glucan
ergosterol
how are spores dispersed?
air
water
vector
