Prokaryotes: Eubacteria (bacteria)

what are prokaryotes?

an organism in eubacteria or arches, unicellular with no membrane bound organelles, eubacteria and arches are in different domains so they are different genetic types of prokaryotes

what are stromatolites?

early bacteria fossils made by cyanobacteria, which supports the theory that bacteria has been here for a really long time

what are some features of eubacteria?

cell wall, cell membrane, cytoplasm, DNA, plasmids, ribosomes, flagella, pilli, capsule

What is the function of pilli?

when two prokaryotes share DNA, the pilli sticks together to communicate with other bacteria

what are flagella?

helps with movement

what is the function of the capsule?

protection

What are plasmids?

circular DNA in cytoplasm

what are some benefits of bacteria?

helps with digestion, helps to decompose things, helps with nitrogen fixation, and food production (cheese)

what are bacilli?

rod shaped bacterial cell

what are cocci?

round bacterial cell

what are sprillia?

spiral shaped bacterial cell

what are the eubacteria arrangements?

mono: single, diplo: pair, staphylo: clumps, strepto: strings

what are obligate aerobes?

require oxygen to produce energy

what are facultative anaerobes?

organisms that can live with or without oxygen

what are obligate anaeorobes?

organisms that cannot survive with oxygen, but can make energy in the presence of other gases
