Terms
undefined, object
copy deck
- extreme holaphiles
- live in highly saline envrionment
- introns
- present in archaea and eukarya; rare in bacteria
- nuclear envelope
- present in eukarya
- histones
- present in arch and euka no in bacteria
- methagens
- unique way to obtain energy; produce methane from carbon dioxide and hydrogen ; live in swam and marshes
- bacterial cell structures
- nucleoid, fimbria, plasmid, ribosomes, plasma membrane, cell wall, flagella, capsule, cytoplasm
- plasma membrane
- for prokaryotes location of resperation. photosynthesis; detection of chemotaxis
- components of prokaryotic cell
- plasma membrane, gas vacoule, ribosomes, inclusion bodies, nucleoid, periplasmic space, cell wall, capsule and slime layers, fimbriae and pili, flagella, edospore
- endospores
- are DNA and a portion of cytoplasm(ribosomes) encased in a tough cell wall; resistant to extreme in temp, drying, and harsh chemicals; comoponent of a prokaryotic cell
- inclusion bodies
- in prokaryotic cells ;storage of phosphate groups, carbon and other stuff
- membrane enclosed organelles
- present in eukarya
- obligate anaerobes
- are poisened by oxygen
- photoheterotroph
- energy source light; carbon source organic compounds
- nitrogen fixation
- convert atmospheric nitrogen to ammonia; usually prokaryotes do this
- chemoautotroph
- engergy source is inorganic molecules; carbon source is CO2
- obligate aerobes
- use oxygen for cellular respiration and cannot grow without it
- formylmethionine
- initiator a.a. for protein synthesis in bacteria
- prokaryotes
- found in domain bacteria and archaea
- peptidoglycan in cell wall
- present in bacteria
- eukaryotes
- eukaryotes
- extreme thermophile
- live in very hot enviroments
- capsules and slime layers
- in prokaryotic; cells resisting to phagocytosis adherence to surfaces
- response to antibiotics streptomycin and chloramphenicol
- archae and eukarya, growth not inhibited; bacteria growth inhibited
- facultative anaerobes
- use oxygen if present but can also grow by fermentation in anarerobic environment
- prokaryotic cell
- a type of cell lacking a membrane enclosed nucleus and membrane enclose organelles. found in bacteria and archae
- rna polymerase
- bacteria; one kind and archaea and eukarya have several
- ubranched hydrocarbons
- membrane lipids in bacteria
- gas vacoul
- in prokaryotic cells allows for buoyancy for floating in aquatic environments
- chemoheterotroph
- energy source organic compounds; carbon source organic compounds
- some branched hydrocarbons
- membrane lipids of archaea
- photoautroph
- energy source is light; carbon source is CO2
- nitrogen fixation
- absent in eukaryotes
- archael cell walls
- diff from bacterial cell walls because they have no peptidoglycan; it is made of lipids whose hydrocarbon attach to glycerol in an ether linkage
- sterols
- present in eukarya
- ether bond
- Any of a class of organic compounds in which two hydrocarbon groups are linked by an oxygen atom; hc chains attache to glycerol instead of fatty acids
- ability to grow at temperatures below 100c
- only in archaea
- frimbria and pilli
- mating things for prokaryotic cells
- unbranched hydrocarbons
- membrane lipids of eukarya
- circular chromosome
- not present in eukarya
- the three domains of life
- bacteria, archea, eukaryae
- methogenesis
- present in archae
- methionine
- I.A.A. for protein synthesis for archae and eukarya
