Final answer:
Bacteria are prokaryotes with no nucleus, while fungi are eukaryotes, which can be unicellular or multicellular with a true nucleus. Fungi have cell walls made of chitin, not cellulose. Bacteria and Archaea, not fungi, consist of prokaryotic cells.
Step-by-step explanation:
Both bacteria and fungi can have different cellular structures. Bacteria belong to the domain Prokaryotes and are composed of prokaryotic cells, which are unicellular organisms that have no nucleus. On the other hand, Fungi are part of the Eukaryotes and can be either unicellular or multicellular organisms, but all consist of eukaryotic cells with nuclei. Fungi are known to have chitin in their cell walls, which distinguishes them from plant cells that have cellulose.
When referring to organisms that consist of prokaryotic cells, we are referring to Bacteria and Archaea, which are single-celled and do not contain a true nucleus. Eukaryotic cells, such as those found in animals, plants, fungi, and protists, do have a true nucleus and more complex cell structures. Therefore, the answer to the question is that fungi cannot be prokaryotic and are instead eukaryotes.
