Answer

Prokaryotes and eukaryotes are two fundamental types of cells. Prokaryotes are single-celled organisms without a true nucleus or membrane-bound organelles. They have a simple structure and are represented by bacteria and archaea. Eukaryotes, on the other hand, are organisms whose cells have a true nucleus enclosed within a nuclear membrane and contain membrane-bound organelles. Eukaryotes include a wide range of organisms, from single-celled protists to complex multicellular organisms like plants, animals, and fungi. All multicellular organisms belong to the group of eukaryotes, as they are composed of cells with a true nucleus and membrane-bound organelles.
