fungi
What is ectomycorrhizal fungi?
annelids, nematodes, and platyhymenthes are what worms
annelids: segmentedw worms, nematods: round worms, platy: flatty
what are choanoflagellates
closest relatives to animals, unicellular, aquatic, has flagellum
what phylums are deuterostomes what phylums are protosotomes
- protostomes: porifera, ctenophora, cnidaria, platyhelmenthes, annelids, mollusks, nematodes, arthropods, echinoderms, chordates
- deuterostomes: echinoderms, chordates
which chordata are jawless
lampreys and hagfish
exchanges nutrients by penetrating cells.
what is arbuscular mycorrhizal fungi?
coelom difference in the three different worms
flatworms: acoelomate, roundworms (nematodes): pseudocoelomate, segmented: coelomate
protosotome groups and what they are
porifera: sponges (multicellular, suspension feeders)
cnidaria: jellies, coral and anemones (polyp and medusa, radial symmetry, diploblast
platy: flat worms, acoelomate, cephalization
annelids: segmented worms coelomate, triploblast
mollusks: snails and clams, radula, foot, mantle
nematodes: round worms, pseudocoelomate
arthropods: crusteceans, spiders, and insects, molt, jointed limbs
reptiles are what?
exothermic, birds though are endothermic
what is the structure and function of fungi?
Hyphae: structural component,
Mycelium: network for nutrient absorption,
Septa: separate hyphae cells,
Spores: asexual and sexual reproduction.
phylogeny derived traits?
platyhelmenthes: loss of a coelom
annelids: segmentation
nemotodes: just basic protostomes ( bilateral, triploblastic, cephalization)
what deuterostomes dont have jaws, which ones have jaws, lobed fins, limbs with digits, and amniotic eggs
- hagfish and lampreys
- reptiles and mammals
what are the four phylogenies of fungi?
- Chytrids: aquatic, flagella
- zoopagomycetes: produce sporangium with tough outercoat
- cryptomycetes: single celled, parasites, motile gametes and spores
- basidiomycetes: forms mycelia, produces club shape structure where spores are formed
nemtaodes
- bilateral symmetry
- 3 tissue layers
- complete mouth
what phylums have triploblastic, cephalization and bilateral symmetry
platyhelminthes, annelids, mollusks, nematodes, arthropods, echinoderms, chordates
what are the four nutritional modes of fungi?
- Decomposers: break down organic material, no associations.
- Parasites: obtain nutrients at a hosts expense.
- Mutualistic: obtain nutrients and also help host.
- Commensionalists: obtain nutrients, do not help or hurt host.
