1. Be able to differentiate between a prokaryotic cell and eukaryotic cell: anaerobic and aerobic respiration; autotrophic and heterotrophic feeding. Prokaryotic cells lack nucleus and other membrane-bound organelles such as mitochondria. Eukaryotic cells are significantly larger and have DNA inside of a nucleus. Anaerobic metabolism does not require oxygen to produce energy. Aerobic metabolism requires oxygen. We have an aerobic metabolism. Autotrophic feeding involves organisms that can produce their own food, such as plants. (photosynthesis) Heterotrophic feeding involves organisms that must consume other organisms for energy. 2. What major feature do members of the Domain Bacteria and the Domain Archaea have in common? How can Bacteria be differentiated from Archaea? The major common characteristic of these two domains is that they are both prokaryotic. The easiest way to differentiate between bacteria and Archaea is that bacteria have cell walls with peptidoglycans.
