Diversityyy Flashcards
origins of fungi
aqautic flagellenated organisms
what are the three main components of fungi?
chitin - cell wall
ergosterol - found in the cell membranes and indicator of fungal presence
mycellium - interconnected tubes (single filament is hyphae)
function of hyphae
they absorb nutrients via vegetative spread and enzyme secretion
large s.a. ideal for absorption
What are Cords?
aggregates of hyphae that are intertwined and can move nutrients and water
> equivelent to xylem+phloem
they are DYNAMIC so can respond to the system
basidiomycota strucuture
4 basidiospores on a basidium
ascoymycota spore structure A 4 spores on a basidium B flagellanated spores C spores in a sac D asexual spores E thick walled spores (zygospore)
OPTION C
ascospores In a ascus (SAC)
a- badiomycota
b-blasto and chytri
d-glomerulomycota
e- zygomycota
how do fungi spread?
spread via spores or they grow out (non-restrictive units)
how do fungi feed?
via carbon fixation.
saprotophs
necrotrophs
biotrophs
can you say the human K P C O F
animalia | chordata | mammalia | primates | hominidae |
which phyla are radiata
placozoans, ctenophores and cnidarians
what makes an animal
they are motile and heterotrophs
they are also multicellular and have a nervous system
they can be ALL be traced back to a common ancestor (not a clade)
what is a deutorostome
what is protosome
protosome is where the mouth develops first then anus
deutorostome is the mouth second
what is unique about chordata?
this is where humans descend from. they are the only deutorostomes in the bilaterian category
what is the difference between annelids and nematodes?
nematods are not segmented
which phyla are ectyzoans?
arthopods and nematodes
> they have a three layered cuticle to exchange gases at the gut
