BIO1108 EXAM 1 TEST PREPARATION
QUESTIONS WITH CORRECT
ANSWERS
secondary endosymbiosis - Answer- a photosynthetic protists is engulfed by a
eukaryote (resulted in chloroplasts and mitochondria)
colonial - Answer- a collective life form comprised of individual organisms
multicellular - Answer- an organism comprised of more than one cell
phagocytosis - Answer- engulfment of a cell or cell fragments by another cell
sessile - Answer- non-motile
amoeboid motion - Answer- performed by pseudopodia; stream forward and the rest
follows
haploid life cycle - Answer- gametes (n + n) --> zygote (2n) --> spore (n) --> mature
organism (n)
diploid life cycle - Answer- gametes (n+n) --> zygote (2n) --> mature organism (2n)
alternation of generations - Answer- gametes (n + n) --> zygote (2n) --> sporophyte (2n)
--> spores (n) --> gametophyte (n)
gametes - Answer- mature female or male germ cells that unite with another of the
opposite sex to form zygotes; sperm and egg; n
spores - Answer- haploid reproductive cell that gives rise to a gametophyte; n
gametophyte - Answer- haploid adult
sporophyte - Answer- diploid adult
green algae - Answer- Lineage Plantae; photosynthetic
unicellular, multicellular, or colonial
have flagella and chloroplasts
red algae - Answer- Lineage Plantae; photosynthetic
unicellular, multicellular, or colonial
have flagella and chloroplasts
, live in marine habitats and aid in the development of coral reefs
brown algae - Answer- Lineage Stramenopila; photosynthetic
multicellular
has flagella and chloroplasts
alternation of generations
diatoms - Answer- Lineage Stramenopila; photosynthetic
glass-like shells, flagella
most important primary producer in fresh and salt water
dinoflagellate - Answer- Lineage Alveolata; photosynthetic
have alveoli, cilia/flagella
bioluminescent, have harmful algal blooms
euglenids - Answer- Lineage Excavata; photosynthetic
has an excavated feeding groove on the side
swim via flagella
abundant in freshwater plankton
ciliates - Answer- Lineage Alveolata; heterotrophic via ingestion
have alveoli and cilia
in freshwater, marine, and wet soil environments
water molds - Answer- Lineage Stramenopila; mostly saptotrophic, some parasitic
has flagella
mature ones are sessile
important decomposers in freshwater
apicomplexans - Answer- Lineage Alveolata; parasitic
have alveoli, cilia/flagella
amoeboid motion
amoeba - Answer- Lineage Amoebozoa; photoynthetic (maybe)
lack cell walls, have a flexible cell membrane
amoeboid motion with cytoplasmic streaming
charophytes - Answer- stoneworts; division of freshwater green algae
cuticle - Answer- acts to slow loss of water from tissues but prevents gas exchange
stomata - Answer- pores that allow gas exchange in photosynthetic tissue
lignin - Answer- provides rigidity; helps resist against gravity and winds
gametangia - Answer- multicellular organs where gametes develop
