Final answer:
Protozoans, fungi, and helminths consist of eukaryotic cells, which have a nucleus and membrane-bound organelles. Archaea and bacteria are made up of prokaryotic cells, which lack these structures. Viruses do not have a cell structure and are not included in the category of eukaryotic or prokaryotic.
Step-by-step explanation:
Microorganisms can be classified based on their cellular structure into two broad categories: eukaryotic and prokaryotic cells. Eukaryotic cells have a nucleus and other membrane-bound organelles, while prokaryotic cells do not.
Protozoans, fungi, and helminths are all examples of microorganisms that are made up of eukaryotic cells. Protozoans are unicellular organisms with a complex cell structure. Fungi can be either microscopic, like molds and yeasts, or multicellular.
Helminths are parasitic worms and are included in microbiology because their eggs and larvae stages are often microscopic. On the other hand, Archaea and Bacteria are prokaryotic and lack a nucleus. Viruses are not considered cellular organisms because they do not have a cell structure, though they can infect eukaryotic or prokaryotic cells.
Therefore, the microorganisms made up of eukaryotic cells from the options given are B) Protozoans, D) Fungi, and E) Helminths.
