BIO 202 EXAM 2 COMPLETE TEST PAPER
QUESTIONS AND CORRECT ANSWERS
◉ polyphyletic.
Answer: group of tax belonging to 7 different super groups
◉ importance.
Answer: algae generate 50% of earths O2
oil deposits formed from ancient algal deposits
◉ biotechnology and disease of protist.
Answer: waste, cleaning, bio-fuels
malaria, giardia, dysentary, brain-eating amoeba
◉ groups of protist.
Answer: ecological role
habitat
motility type
◉ algae ecological role.
Answer: autotrophs( photosynthetic), produce O2 as a by product
,importance source of renewable biofuel
◉ fungus-like ecological roles.
Answer: heterotrophs, characters shared w/ true fungi through
convergent evolution, water molds
◉ protozoa habitat.
Answer: heterotrophic, feed by absorbing or ingesting food items
◉ plankton habitat.
Answer: in fresh and salt water, also includes viruses, bacteria, small
animals, phytoplankton are photosynthetic, mostly unicellular, some
colonial or multicellular
◉ aqautic substrates habitat.
Answer: macroalgae (seaweed) large photosythetic protist
most are multicellular, with different cell types
some are very large
most seaweed grows in shallow water
attach to nearly all substrate
generates large amounts of O2
uses food, fertilizer, commerical products
,◉ motility types: flagellum.
Answer: whip like
mostly unicellular, some w few cells
2-20 microns long
not powerful
can also collect bacteria to eat
◉ cilliates.
Answer: cillia: short, miroscopic, hair like
have larger bodies the flageolates
◉ amoebea.
Answer: crawling movement by protrusion of cytoplams of cell via
formation of puesodopodia, shape changes during movement
◉ ecata or discoba.
Answer: unicelluar, very diverse; aerobes, anerobes, symbionts,
parasitles, free-living, bacterivores, photosynthetic
◉ synapomorphy ecavata or discoba.
Answer: excavated feeding group (what they all have in common)
, ◉ phangocytosis.
Answer: plasma membrane vesticle surrounds food--> pinches off
within cytoplasm, enzymes then breakdown for food digestion
◉ euglenoids.
Answer: colorless or green, lack or possess chloroplast and have
light-seeing eye spot= allows them to move towards light in wetland
◉ kineoplast.
Answer: network or circular DNA inside a large mitochondrion
◉ metamonads.
Answer: some are parasites that attack host cells for food
◉ SAR clade.
Answer: alveolata, stramenopila, rhizaria
◉ synapomorphies of the SAR clade.
Answer: photosynthetic plastiods around aquired via 2-3 degrees air
filled sacs
