BIOLOGY LAB 172 2026 EXAM WITH
QUESTIONS AND ANSWERS
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
, 2 |Page
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
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
