It has to do everything for itself. Also has a certain number of parts with which to change its engineering, thereby changing its function. In Cell Biology what can limit the progress of science? - Correct Answers technology A single-celled eukaryotic organism: - Correct Answers Has a limited number of biomolecular machines. Must find food, shelter, a mate and reproduce Escape from predators Comparing a single-celled eukaryotic organism with a multicellular organism such as yourself identify the major difference from the list below. - Correct Answers Division of labor
