Prokaryotic organisms first evolved on the earth. Many differences exist between the prokaryotic and eukaryotic organisms. Hence, their cellular structures and compartmentalization also vary. The functions and the biochemical pathways also vary from each other. The eukaryotic cells possess different types of organelles. The prokaryotic cells do not have all of them. Most of the prokaryotic cells possess microscopic and sub-microscopic structures. These cells do not get visualized with the naked eyes. The only way to study them involves culturing them and visualizing them under a microscope. The eukaryotes, on the other hand, show a wide range of organisms such as plants, insects, animals, birds, and human beings. The eukaryotic organisms possess different types of bodies, different cells, different proteins, and cellular processes. Thus, both prokaryotic and eukaryotic cells involve topics of interest for the researchers. Let us discuss the different points.
