Document Summary
In some rare cases, they could kill you e. g. plague. A current view of the tree of life: 3 domains of life very diverse, bacteria (prokaryotes) massive branch, archaea (prokaryotes, eukaryotes. Prokaryotes: the smallest, simplest, and most abundant cells on earth. Include bacteria and archaea: human cell in lab black dots are bacteria example of one with intracellular life cycle. Makes protein that pushes around the cytoplasm to hide from immune system learn later. Bacterial classification by shape: coccus: round, spherical e. g. streptococcus (reflected in name, rod: rod, elongated (e. g. salmonella, spirillum: curved (e. g. lyme disease, there are other shapes, but those are the major three. Escherichia coli diversity: ca(cid:374) se(cid:395)ue(cid:374)(cid:272)e the ge(cid:374)o(cid:373)e of t(cid:449)o diff e. (cid:272)ol"s, they may only be 60% identical even though they are the same species. Basic bacterial cellular structure: cytoplasmic membrane the membrane that surrounds cytoplasm, cell wall, cell envelope just consider to be everything from the cytoplasmic membrane out.
