Diff's B/T Prokaryotic and Eukaryotic| Section 4.5 Saturday, December 01, 2007 2:19 PM Prokaryotes: No Organelles, first were similar to modern prokaryotes, live on more diverse energy sources, Bacteria, & Archaea, Generally smaller, single cell, often in clusters though, nucleoid contains DNA, FUNCTIONALLY COMPLEX, carrying out thousands of biochemical reactions. Some have cell walls, internal membrane for some chemical reactions, flagella, peptidoglycan, ribosome's, cytoplasm, capsule. Some carry out photosynthesis like cyanobacteria. Eukaryotes - Protists, Plants, Fungi, Animals, has a nucleus, contain organelles, plasma membrane, cytoplasm, ribosome's, up to 10x greater, mitochondrion, endoplasmic reticulum, Golgi apparatus,

Unformatted text preview: lysosomes, vacuoles, chloroplasts, nucleolus, Endosymbiosis - Early Prokaryotes engulfed other prokaryotes that lived within them, they're offspring contained two prokaryotes also, some say mitochondria were result of engulfed prokaryote. The smaller prokaryotes that gave rise to organelles gradually lost much of their DNA to the nucleus of the larger cell. Support for theory - evidence of movement of DNA between organelles in eukaryotic cell, many biochemical similarities between chloroplasts and photosynthetic bacteria, DNA sequencing sows strong similarities between modern chloroplast DNA and photosynthetic prokaryote....
