What are the kingdoms? - Answer✔Animalia, plantae, fungi, protista, monera (archaea and
bacteria)
Which kingdoms are prokaryotic? - Answer✔monera (archaea and bacteria)
Which kingdoms are eukaryotic? - Answer✔Animalia, plantae, fungi, and protista
Eubacteria is... - Answer✔unicellular and prokaryotic
archaeabacteria is... - Answer✔unicellular and prokaryotic
protista is... - Answer✔eukaryotic and either unicellular or multicellular
plantae is... - Answer✔multicellular and eukaryotic
animalia is... - Answer✔multicellular and eukaryotic
Fungi is... - Answer✔multicellular and eukaryotic
How each eukaryote gets their food - Answer✔plants-photosynthesis
fungi- absorption
animalia- ingestion
Prokaryotes - Answer✔-unicellular (except for biofilms)
-no nuclear membrane
-no organelles
-no cytoskeleton (no mitosis) they cant make chromosomes
Archaea - Answer✔archaeabacteria, methanogens, extreme halophiles, extreme thermophiles

Archaea: archaeabacteria - Answer✔inhabit extreme environments, live in places where no one
expected things to live (geysers)
Archaea: methanogens - Answer✔-anaerobic (without oxygen) decomposers that convert Co2
and H2 to methane
-inhabit swamps, guts and, sewage guts of cattle black swamp guck
-release 2 billion tons of methane a year
Archaea: extreme halophiles - Answer✔-highly salt tolerant
-live in brine lakes up to 25-35% saline (sea water is 3.5% saline)
Archaea: extreme thermophiles - Answer✔-tolerate high temperatures (60-80 c)
-perhaps closest of the prokaryotes to eukaryotes based on their genome structure
Bacteria: Nitrogen fixing bacteria - Answer✔-convert atmospheric N2 (nitrogen) to compounds
usable by plants
-live in roots of plants (legumes)
Bacteria: cyanobacteria - Answer✔-one of the first photosynthesizers (chlorophyll a)
Bacteria: chemoheterotrophs - Answer✔-facultative anaerobes includes gut bacteria
Bacteria: intercellular parasites - Answer✔commonly causes diseases
How does bacteria reproduce? - Answer✔by fission
parent transmits genetic material to daughter cells
prokaryotic reproduction=cell division
their chromosomes are circular
Extrachromosomal DNA - Answer✔Plasmids-small, circular, double stranded DNA molecules
(carry genes)
genes carried in plasmids can provide bacteria with genetic advantages
-antibiotic resistance
bacteria that has plasmids are positive
Horizontal Gene transfer - Answer✔plasmids can also be transferred among bacteria by
CONJUGATION independent of fission
(little disk unwinding looking thing to the other cell)
