Diversity of Form and Function
exam #1 part 1 Questions with
Correct Answers
Gram + Bacteria - Correct Answer: Abundant peptidoglycan in cell wall
Ex: endotoxins
Gram - Bacteria - Correct Answer: Cell wall under membrane
Quorum sensing - Correct Answer: Coordinate gene expression based on surroundings
Horizontal Gene transfer - Correct Answer: complicates use of sequences to determine phylogenies
Gene transfer to existing phylogeny
Vertical gene transfer - Correct Answer: gene transfer from generation to generation
Conjugation - Correct Answer: DNA transferred from donor cell to recipient by a pilus
Transformation - Correct Answer: DNA released by dead cells is taken up by recipient cells
Transduction - Correct Answer: DNA is transferred from donor to recipient by virus
Proteobacteria - Correct Answer: Most diverse
Anoxygenic photosynthesis
aerobic respiration
Gave rise to mitochondria
Cyanobacteria - Correct Answer: Oxygenic photosynthesis
, Gave rise to chloroplasts
photoautotrophs
Responsible for evolution of O2
Obligate anerobes - Correct Answer: poisoned by O2
Obligate aerobes - Correct Answer: require O2
Facultive aerobes - Correct Answer: Can use either aerobic or aerobic respiration
Anoxygenic photosynthesis - Correct Answer: Use bacteriophyll to harvest sunlight by an oxygenic
photosynthetic bacteria
1 photosystem
Photoautotrophs - Correct Answer: Synthesize food using light as energy
Photoheterotrophs - Correct Answer: Rely on sugars from other organisms but still harvest energy from
sunlight
Chemoheterotrophs - Correct Answer: feed on other organisms for organic materials
Chemoautotrophs - Correct Answer: Feed on other organisms for inorganic molecules
Prokaryotes only
Decomposers - Correct Answer: Break down dead bodies
return carbon to soil/ CO2 to air
Cycle N an S
Nitrogen fixers - Correct Answer: Convert N2 to NH3 for amino acid synthesis
