Document Summary
Wavelength of light doesn"t let you go under this number. So, you got to move down to electrons (wavelength much smaller). Animalia) of life based on physiology and morphology: protista: had the early discovered microbes under the branch called monera. In 20th century, electron and light microscopy advanced cell biology knowledge. Depending on cellular organization, microbes can be: prokaryotic cells: lack membrane bound nuclei, eukaryotic cells: have a membrane-enclosed nuclei and complex organelles, prokaryotes, shapes: cocci (sphere), bacilli (rods, similarity in prokaryotes and eukaryotes: ribosomes in both. This is putting microbes at bottom of the tree of life. In 70"s, carl woese tried to answer the question of tree of life through molecular way. He said that bacteria and archaea are exclusively microbial, while eukarya are only mainly microbial. Most nitrogen is in form of gas so we can"t take it.
