Document Summary
Explains where the morphological features come from that define complexity between organisms. Infolding of the plasma membrane is where the membrane material for the er comes from. There is an advantage for ancestral bacterium to take in aerobic cells that can produce much more atp. Cyanobacteria was engulfed as well, which can take in sunlight and produce more energy. Formation/division: chloroplasts and mitochondria develop from pre-existing chloroplasts and mitochondria that undergo binary fission which splits them in half. Electron transport chains: only organelles that have electron transport chains. Transcription/translation machinery: have the machinery to create proteins and convert dna into necessary components. Many of the genes for the mitochondria and the chloroplast to work have moved to the nucleus, which is known as lateral gene transfer. There needs to be 5,000 proteins for the mitochondria and chloroplasts to work. Just change the location where the genetic information is stored for these organelles; what these genes do has not changed.
