As a result, it is a very diverse group of organisms. The key difference from earlier classifications such as the two-empire system and the five-kingdom classification is the splitting of archaea from bacteria as completely . Organelles may be present in certain protist cells but not others. Sexual reproduction is possible, but typically only occurs during times of stress. Under harsh conditions, plasmodial slime molds produce reproductive stalks called sporangia that contain spores. The four eukaryotic kingdoms are animalia, plantae, fungi, and protista.

Instead of merely dividing themselves and copying their genetic materials (like what other domains do), cell division in eukaryotes involves two processes: mitosis and cytokinesis. True, Eukarya is the only domain with multicellular organisms Eukarya is a domain. Nutrition Acquisition Protists have a variety of ways of obtaining food. The cells of prokaryotes, on the other hand, lack this nuclear membrane.
