The Greek word for kernel is karys, so the word used to…
““The Greek word for kernel is karys, so the word used to describe creatures without a nucleus is prokaryotic—the name, originally procariotique, was coined in the 1930s by Edouard Chatton, a French marine biologist—while creatures with nuclei are eukaryotic. Bacteria are prokaryotes. Pretty much everything else, from yeast to elephants, are eukaryotes. This realization resulted in the creation of a fifth Kingdom, dividing one-celled eukaryotes, who retained the Protist name, from prokaryotes. Thus, by the time the dust had settled, in the 1970s, the hierarchical tree of life had two domains—Prokarya and Eucarya—and five kingdoms: Plantae, Animalae, Fungi, Protista, and Bacteria.*””
