Updated.
3 Domains - Answer Eukarya, Archaea, Bacteria
Mitochondria & Chloroplasts derived from... - Answer Bacteria
Endosymbiosis - Answer 1 bacterium engulfs the other
Lateral transfer - Answer genes move from one species to another (happens in endosymbiosis)
Which stage of endosymbiosis produced the 1st photosynthetic eukaryotes? - Answer Primary
endosymbiosis
Primary Symbiosis - Answer Chloroplast has 2 membranes; a cyanobacterium was engulfed
Primary endosymbiosis gave rise to... - Answer red algae, green algae, & land plants
Secondary endosymbiosis - Answer chloroplast has 3 membranes
Tertiary endosymbiosis - Answer Dinoflagellate lost its chloroplast & took up another protist
that acquired its chloroplast through secondary endosymbiosis
Plantae - Answer The clade of eukarotic life w/ chloroplasts derived form primary
endosymbiosis
What bacteria uses chlorophyll A to produce O2 - Answer Cyanobacteria
Who discovered archaea using phylogenetic analysis of ribosomal RNA? - Answer Carl Woese
Is Eukarya a clade? - Answer yes
Are archaea a clade? - Answer no
, Photoautotrophs - Answer Organisms that use light to generate ATP for carbon fixation
(photosynthesis)
Sporophyte - Answer multicellular diploid organism
Advantages of the sporophyte - Answer Diploid body is more resistant to drying out; genetic
advantage of diploid; will produce many sporangia
Gametes are haploid or diploid? - Answer Haploid
Where are gametes produced? - Answer In the antheridium & archegonium from the
gametangia
Spores haploid or diploid? - Answer Diploid
Where are spores produced - Answer sporangia
Are bryophytes a clade? - Answer no
What makes up the bryophytes? - Answer Liverworts, mosses, and hornworts
Are the bryophytes a clade? - Answer no
Are bryophytes vascular or nonvascular? - Answer nonvascular land plants
How do bryophytes survive on land? - Answer Live in moist habitats
Dominant life form in the bryophytes - Answer gametophyte
Are both the sporphyte and gametophyte independent? - Answer No. The sporophyte is
dependent on the gametophyte for nutrition and usually remains attached
Motile sperm in the bryophytes? - Answer yes
Green, flat leaf-like gametophytes - Answer liverworts
