Document Summary
Differ in size (pro have smaller ribosomes) and antibiotic susceptibility. Occur free in cytoplasm or in association with the rough er. Lysosome: euk only, vesicle containing digestive enzymes (hydrolytic enzymes, figure 6. 13. Site of photosynthesis: use energy in sunlight to fix carbon, oxygen is produced as a by-product. Not part of the endomembrane system three membranes inner and outer membranes thylakoid membrane: stacks are called grana (granum: singular) stroma contain circular, naked dna. Autotrophs: plants, can synthesize all organic material they need. Heterotrophs: animals rely on other ways to get what they need. Endosymboint origin (lynn margulis) these organelles originated from small prok living inside larger cells larger cell and the endosymbiont both benefited figure 29. 3. These organelles have characteristics indicating that they evolved from prokaryote endosymbionts. circular naked dna- pro-like small ribosomes- pro-like. Evolution does not proceed just by small mutations.
