Analyzing microbial life in the rocky mountains

Assume you are analyzing microbial life in the Rocky Mountains. You scoop up a water sample from a melted snow puddle because you are curious about the possible microbes that might live there. Using your microscope, you examine several drops of the sample on microscope slides. Your examination reveals that your melted snow puddle contains two different kinds of cells: one cell type was large with several different internal structures and the other cell type was small and lacked the internal structures of the larger cell. Give the name for each cell type and describe their overall similarities and differences.
