Biology Lab 172 Exam 1 UH Manoa; Questions
and Answers 100% Solved
lichen - crustose Correct answer crust like, tightly attached to substrate
lichen - foliose Correct answer leafy; small rhizines attach lichen to tree or hard surface
lichen - fruticose Correct answer shrublike; often attached at one point; common at high
altitudes
symbiosis Correct answer the long-term interaction between organisms of different
species where at least one or more
of the participants, symbionts, gains some benefit
mutualism Correct answer both species benefit from the relationship
commensalism Correct answer one organism benefits and the other is unaffected
parasitism Correct answer one organism benefits and the other is harmed
algae Correct answer simple, eukaryotic, aquatic photo-autotrophs that range from
unicellular to multi-cellular forms
endosymbiosis Correct answer process where unicellular organisms engulf other cells;
function as organelles within the host cell
kingdom fungi Correct answer a kingdom a of multicellular, eukaryotic organisms, such as
mushrooms and molds, that have a cell wall containing chitin; classified under Domain Eukarya
, Biology Lab 172 Exam 1 UH Manoa; Questions
and Answers 100% Solved
hyphae Correct answer the branching, threadlike tubes that make up the bodies of
multicellular fungi and absorb nutrients
yeasts Correct answer single celled fungi
chitin Correct answer a chemical that provides both toughness and flexibility in the walls
of fungi
division zygomycota Correct answer fast-growing molds that we see on old strawberries,
or Rhizopus stolonifer, a type of bread mold
"fixing" in relation to microscope slides Correct answer kills the specimen and preserves
its structures
asexual reproduction in rhizopus stolonifer Correct answer as long as food sources are
abundant, Rhizopus stolonifer will reproduce asexually; haploid spores (sporophytes or embryo)
are dispersed through the air in large quantities
septate hyphae Correct answer cross-walls separating cells
aseptate hyphae Correct answer no dividing cross-walls (rhizopus stolonifer)
sexual reproduction in Rhizopus stolonifer Correct answer two different genetic strains (+
or -) each release pheromones causing branches to grow towards each other
zygosporangium Correct answer a bulbous structure that develops a thick, tough wall,
enabling it to lie dormant for months
