All living things are made up of a cell or cells, and all cells are either prokaryotic or eukaryotic. A eukaryotic cell is a complex cell with a nucleus and many organelles. Eukaryotic cells are the building blocks of all animals, plants and fungi.Prokaryotic cells are very simple cells with fewer structures than eukaryotic cells; one primary difference is that they lack a nucleus.ibosomes. The only true organelles in a prokaryotic cell are ribosomes, which are cytoplasmic organelles. Ribonucleic acid (RNA) in the ribosomes receives information from the cell's deoxyribonucleic acid (DNA) to create protein.
During the 1950s, scientists developed the concept that all organisms may be classified as prokaryotes or eukaryotes. The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm. However, the cells of prokaryotes are simpler than those of eukaryotes. For example, prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus. Prokaryotic cells lack internal cellular bodies (organelles), while eukaryotic cells possess them. Examples of prokaryotes are bacteria and archaea.
