Document Summary

Anaerobic bacteria (no oxygen in atmosphere or dissolved in water) Later, bacteria get high-energy electrons from various sources. One group bacteria can split water molecule to attain oxygen (as waste product). This ultimately results in dissolved oxygen in water. This is the most efficient way of generating energy, causing this organism to increase in abundance. The bacteria that cannot use oxygen die and take refuge in deep sea hydrothermal vents. Linnaeus gave us only two kingdoms (plants and animals) Later became apparent that there are 5 major morphologies. Can carry out photosynthesis algae (autotrophic: multi-cellular, heterotrophic = animalia, autotrophic = plantae. Two different domains created due to many differences between the two types. Archea: can survive in ocean vents, hot springs, high levels of salt environment, no peptidoglycan, cell membrane has branching carbons with ether links, dna was packaged into histones.
