This is what I learned: Organisms that have a nucleus are called Eukaryotes (pronounced yoo-care-ee-oats). Some examples of eukaryotes are humans and most types of animals, such as zebras or turles. Eukarytoic organisms are animals, plants, fungi, and protists.Organisms that do not have a nucleus and Prokaryotes (pronounced pro-care-ee-oats).Examples of prokaryotes are a type of bacteria (such as Frateuria aurantia) and thermophiles.Prokaryotic organisms can fit into the categories of Bacteria or Archaea.ukarytoic organisms are animals, plants, fungi, and protists. Organisms that do not have a nucleus and Prokaryotes (pronounced pro-care-ee-oats).
