Document Summary

Prokaryote phyla, just gives us an idea of how diverse luca has become. What (cid:449)e"(cid:448)e (cid:271)ee(cid:374) a(cid:271)le to do is dis(cid:272)o(cid:448)er (cid:449)hat lucas ge(cid:374)o(cid:373)i(cid:272) (cid:373)aterial looked like and how it diversified. We ha(cid:448)e e. (cid:272)oli that"s (cid:271)e(cid:374)efi(cid:272)ial i(cid:374) our (cid:271)od(cid:455), a(cid:374)d a(cid:374)other e. (cid:272)oli and devastatingly poisonous. In between, we have the e. coli that we hear about in the summer, hamburger disease. They all look the same, so the(cid:455)"re all (cid:374)u(cid:373)(cid:271)ered, a(cid:272)(cid:272)ordi(cid:374)g to (cid:374)u(cid:373)(cid:271)er of proteins in cell wall, thtas the only way to classify them and tell whats what. Bacterial cells, they have the ideal surface to volume ratio. All the rxns occur are in the cytoplasm (volume), but the supply is coming across the membrane (the surface area), so if you have a small cell, less volume demands supply and vice versa.
