FUNGI - nutrition, reproduction, lifestyle Flashcards
fungi can allocate food for reproduction/fruit bodies steadily or dedicat it all to reproduction. which best fits r slected species
dedicate it all to them.
r-selected fungi makes fruit bodies very quickly or spores, using lots of simple compounds
k-selected fungi make fruiting bodies very slowly
what is a downside to r-selected fruting bodies
they aren’t stress tolerent or good fighters
what is the optimum temperture for fungal spore prodcutino
5 degrees!
BUT this is the mimimum temp for fungal growth/extension
snow mould = pyschrophile
compost = thermophile
but what is a mesophile?
most fungi are mesophiles 15-40 degrees (so in the MIDDLE!)
> APSERGILLUS FUMIGATIS IS A 12-52 so themotolerent mesophile ~odd one out
how does water affect fungi phisology
some may be xerotolerent/phile = can live in dryness
whilst some are extrem sensitve to water
> blastotrio and chytrio mycota have aqautic flagenellated spores!
which of these does NOT influnce fruit body development? A light intenstiy B temperature C co2 conc D gravity E acidity F humdity
acidity doenst
co2 = longer stlak snd shorter caps humidty = short caps as less transpiration
what are the effects of climate change on fruintg season
fruitng seasonis longer! starts earlier, ends later
if one gamete is stationary, this describes
isogamy
oogamy
ansiogamy
OOGAMY - e.g. sperm moves but ovum is still
isogamy = same size gamtes ansiogamy = uneven sizes gamte
what is the fungal tube structure that male nuclei move through to fertilsie female stamen style trichiogyne epididymis pollen tube
OPTION C - key word fungi
