Biol 1202 Exam 2 Questions with
Detailed Verified Answers
Photoautotrophs Ans: use energy to synthesize organic compounds
presence of plasma membrane
lack of a nuclear envelope Ans: Which of the following traits do archaea and
bacteria share?
Light and CO2 Ans: What do photoautotrophs use as an energy and carbon
source?
Gram-positive bacteria-symbionts in legume root nodules Ans: Which
prokaryotic group is mismatched with its members?
Eukaryotic Ans: Protists are all alike in that all are
mitochondrion and chloroplasts Ans: the strongest evidence for the
endosymbiotic origin of eukaryotic organelles is the similarity between exact
prokaryotes and which of the following?
Cyanobacteria-->green algae-->green plants Ans: the chloroplasts of modern
plants are though to have been derived according to which sequence?
It engulfs organic material by phagocytosis Ans: A mixotroph loses its plastid
yet continues to survive. Which of the following most likely accounts for its
continued survival?
ciliates- red tide organisms Ans: Which of the following is mismatched?

dinoflagellates Ans: Which group(s) within alveolates include(s) members that
are important in ocean food webs, cause red tides that kill many fish, and may
even be carnivorous?
Ciliates Ans: You are given an unknown organism to identify. It is unicellular
and heterotrophic. It is motile, using many short extensions of the cytoplasm,
each featuring the 9 +2 pattern. It has well-developed organelles and three
nuclei, one large and two small. This organism is most likely to be a member
of which group?
Conjugation Ans: Which process results in genetic recombination, but is
separate from the process wherein the population size of paramecium
increases?
diatom Ans: A certain unicellular eukaryote has a siliconous (glasslike) shell
and autotrophic nutrition. To which group does it belong?
Apicomplexans- parasite Ans: Which of the following correctly pairs a protist
with one of its characteristics?
Brown algae Ans: The largest seaweed belongs to which group?
are unicellular Ans: Members of the green algae often differ from members of
the plant kingdom in that some green algae
Almost all eukaryotes have mitochondria, while only autotrophic eukaryotes
generally have plastids Ans: Biologists suspect that endosymbiosis gave rise
to mitochondria before plastids partly because
Forams- ciliated algae with numerous micronuclei Ans: Which organism is
incorrectly paired with its description?
