Document Summary
The domains of life: we are always covered with bacteria archaea no human infections there are some in human intestines. Prokaryotes: prokaryotes are the smallest, simplest and most abundant cells on earth, prokaryotes include bacteria and archaea estimated ~5 x 1030 prokaryotes on earth, prokaryotes lack a nucleus and complex organelles. No nuclear membrane, and no membrane bound organelle: bacteria are very small compared to our cells. Bacteria can grow fast: bacteria reproduce by binary fission. Genetically identical daughter cells: 4 phases of growth. Stationary running out of nutrients, produce acids that are toxic for them. Simply means how long does it take to double some species grow fast (double in ~10 minutes) grow extremely fast compared to more complex organisms some species grow slow (double in ~24 hours) Bacterial classification by shape: coccus sphere, name of bacteria might refer to their shape, rod. Might look the same under the microscope.
