BIO 321 EXAM 2 PREP QUESTIONS WITH
CORRECT ANSWERS
3 Organelles of the Diatom Rhopalodia - correct answer- 1)
Chloroplast (Cyanobacteria)
2) Mitochondria
3) Spherical bodies - endosymbiosis cyanobacteria that fix
nitrogen for the alga
A secondary Primary Endosymbiotic Chloroplast - correct
answer- Paulinella
Acetabularia 'Mermaids wine glass' - correct answer- Grows
in warmer salt water. For most of its life the 'wineglass' is only
one cell. This species was where mRNA was first identified.
Adaptation to light quality - correct answer- Cyanobacteria
can vary the composition of the phycobilins to adapt to different
light environments.
Algae - what's for dinner? - correct answer- Water does not
absorb all wavelengths of light equally
,Blue goes deeper
Then purple
Then green
Algal Organization - Macroscopic - correct answer-
Rhodophyta
Viridiplantae
Phaeophyta
Algal Thallus Anatomy - correct answer- Blade
Transition Zone
Stipe
Holdfast
Anabaena - correct answer- lives inside pockets in the fern
leaves
Anabaena symbiosis with Azolla - correct answer- The
Anabaena fixes nitrogen and the Azolla thus becomes N rich
Azolla is used as "green manure" on rice fields instead of
fertilizer
,Anisogamy - correct answer- Gametes of different sizes.
Usually the egg is much larger and contains nutritional material.
Aphotic - correct answer- No light
Archaeplastida - correct answer- Glaucophyta
Rhodophyta
Viridiplantae-Chlorophyta & Streptophyta
Articulated and Non-articulated (Crustose) Coralline Algae -
correct answer-
Asexual reproduction in Volvox - correct answer- See
Diagram
New colonies undergo inversion to orient the flagella on the
outside of the colony.
These new colonies are released from the inside of the parent
colony by the senescence of the parent colony.
Autotroph - correct answer- Use light as energy source
(photo autotroph)
, Azolla - correct answer- water fern
Bangiophyta - Nori wrap - correct answer- Made primarily
of Porphyra
Bangiophyta - Porphyra - correct answer- Thin blades that
can be one or two cells thick
Bi-phasic life cycle (Diplohaplontic)
Bangiophyta Life Cycle - correct answer- See diagram
Biodiversity of Algal Pigments - correct answer- See Chart
Branching: Dichotomous - correct answer- Divide into 2
Branching: Whorled - correct answer- (Pine trees)
Calcareous green algae: - correct answer- Halimeda
Calcareous plates
