BSC2011L USF Lab Midterm Questions With Complete
Solutions
akinetes Correct Answers thick walled dormant cells
specialized for survival (in cyanobacteria)
angiosperm Correct Answers dominated Cretaceous period
flowering plant
phylum: anthophyta
Clade Alveolata Correct Answers have alveoli
dinoflagellates
exhibit taxis
Stentor
paramecium
clade rhizaria Correct Answers planktonic marine algae
narrow pseudopodia
foraminifera, radiolarians
clade stramenopila Correct Answers straw-like hairs
cycle 25% carbon on Earth
brown algae, giant seaweeds
Convergent evolution Correct Answers acquisition of similar
biological traits in unrelated lineages
cotyledons Correct Answers embryonic seed leaves
, Describe cyanobacteria Correct Answers photosynthetic
(autotrophs), contain chlorophyll a, phycocyanin, and
phycoerythrin
dicots Correct Answers two cotyledons and endosperm absent
in mature seeds
dioecious Correct Answers separate male and female plants that
produce either ovules and seeds or pollen BUT not both
Divergent evolution Correct Answers accumulation of
differences among reproductively isolated groups that evolved
from a common ancestor
double fertilization Correct Answers (angiosperm) each pollen
grain produces two sperms; one sperms fuses with the egg and
the other two fuses with two polar nuclei found in ovary to form
triploid tissue
endosperm Correct Answers (angiosperm) triploid tissue
evolution Correct Answers a change in allele frequencies
throughout generations
The gradual change in a species over time
The gradual change in a species over time
female _________ Correct Answers megaspore; develops into
female gametophyte which is retained in the megasporangium
and nourished by sporophyte parent
fiddlehead Correct Answers an uncurling frond
