Explanation:
Detailed explanation-1: -Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.
Detailed explanation-2: -The characteristics of prokaryotic cells are: Membrane bound cell organelles such as Mitochondria, Golgi apparatus, Chloroplasts are absent. A membrane bound well defined nucleus is absent. Genetic material is circular DNA and occurs naked in the cell cytoplasm.
