First off, know that the whole division into kingdoms idea has been removed. All living creatures are now separated into domains: Bacteria, Archaea, and Eukarya. Still, I can provide a few for each category.
Monera is all the bacteria and archae bacteria in the world. They are all prokaryotes and therefore have no nucleus. Some examples are the certain diseases, such as Streptococcus pneumoniae (the bacteria that causes pneumonia) and Micobacterium tuberculosis (which causes tuberculosis).
Fungi are all the fungi of the world, all of which are eukaryotes that exist in both diploid and haploid stages. They include all the mushrooms of the world and molds like the bread mold, Rhizopus stolonifer.
Protists are extremely diverse, many being eukaryotes, though some are prokaryotes, and some being unicellular while others and multicellular. They are divided into three categories, protists (animal-like), which include Amoeba, algae (plant-like), which include Ulva, and fungus-like, which include chytrids.
Emphasize progress in a realistic manner.
