Document Summary
Defining characteristic of eukaryotes, energy transducing organelles, nuclear envelope. Endomembrane system: comes from infolding of plasma membrane. Endosymbiosis: mitochondria and chloroplasts are descendants from free-living prokaryotic cells. Cyanobacteria: group of mitochondria containing cells, took up other prokaryotes and made it the chloroplasts. Morphology: way they divide, shape, size, similar to prokaryotic cells. Formation/ division: similar to bacterial division: no genes that build mitochondria, old mitochondria and chloroplasts divide. Electron transport chains, no other organelles have this. Genomes: have own dna, code for proteins needed to help organelle function. Prokaryotes that undergo aerobic respiration: cells took up these organisms because they make lots of atp. What is the diffference in atp production b/w anaerobic/aerobic. Thru endosymbiosis cell overcame energy barrier: more atp made. High pm surface are/ volume ratio: etc on pm, there"s other things of pm as well, so finite amount of are that can be dedicated to energy production, constricts volume.
