Document Summary
Nothing eukaryotic about these processes : dna recombination, introns and exons, nucleus-like structures, dynamic cytoskeleton, intercellular signaling, endocytosis. Rare in bacteria/archaea, also usually only one of these. Neither bacteria or archaea show any tendency towards morphological complexity. Morphological complexity different tissue types, you can do different things. Earliest forms of life were anaerobic (glycolysis, fermentation, 4 billion years. Cyanobacteris (2. 2 bya) oxygenic photosynthesis like plants rise of oxygen. Leads to bacteria that undergo aerobic respiration linked to energy respiration of ago) that is a great electron acceptor cell. It"s really about power (watts) o: proton motive force (pmf) how much potential energy is in a proton gradient (mvolts . watts) Force comes from the fact that there is an concentration difference. How much power a cell can generate it important to the evolution of life. Mitochondria increases surface area, internalized chemiosmosis. Bigger bring in bigger molecules, eat others more than they eat you.
