Know characters that separate prokaryotes from eukaryotes o Prokaryotes- Have DNA simply floating in the cytoplasm, a plasma membrane, ribosomes, a cell wall, and flagella. Usually smaller organisms like bacteria. o Eukaryotes- Have: A nucleus that encloses the DNA Organelles such as mitochondrion, plastids, a plasma membrane, and so on. Usually more complicated organisms. What are the two proposed routes of evolution: o In-foldings of plasma membrane. o Endosymbiosis- Some organelles previously were seperate organisms that became a part of the cell. Evidence showing this is: Organelles similar in size. Enzymes and transport systems resemble modern prokaryotes. Circular DNA lacks histones and other proteins.
