COMPARING PROKARYOTES AND EUKARYOTES DISTINCTIONS SIMILARITIES Prokaryotes 1

COMPARING PROKARYOTES AND EUKARYOTES DISTINCTIONS SIMILARITIES Prokaryotes 1. All bacteria. 2. Complexity at 106. 3. No nuclear membrane. 4. Single, circular chromosome. 5. Devoid of membrane bound organelles. 6. Reproduce by fission. 7. Flagella for locomotion. Eukaryotes 1. Life is the basic properties of both cells. 2. Cultured and reproduced for extended periods. 3. Highly complex and organized. 4. Similar genetic program and protein synthesis machinery. 5. Acquire and utilize energy: similar reactions and via ATP. 6. Reproducing genetically identical daughter cells. 7. Capable of locomotion. 8. Response to stimuli in environment. 9. Capable of self regulation. 1. Protists, fungi, plants, animals. 2. Complexity at 109. 3. True membrane bound nucleus. 4. Many chromosomes made of DNA and protein. 5. Membrane bound organelle and cytoskeleton proteins. 6. Reproduce by mitosis. 7. Cytoplasmic movement, cilia and flagella for locomotion.
