![]() Their most distinctive feature is that the bits which keep them going, each and every water-soluble cog in their chemical mechanisms, are all mixed together in the internal cytoplasm. Out of the two groups, prokaryotes are the oldest and arguably boast the simplest internal layout. The prefix pro, which means before, basically tells us that prokaryotes came ‘before kernels’ - because they sprang alife before the nucleus evolved. Their eukaryote counterparts, by contrast, are ‘true-kerneled’ organisms (the prefix eu means ‘true’), as they have nuclei. Both words are drawn from the ancient Greek root-word karyon, meaning ‘nut’ or ‘kernel’. ![]() The single most all-encompassing feature by which we classify cells is the way they order their internal structures, of which there are two overarching models: prokaryotic and eukaryotic. Since that’s probably very confusing, let’s take a more in-depth look at the different types of cells out there. The short answer is ‘the power of friendship’ and ‘yes’. So what makes them so special, and are there any other kinds of cells wiggling around? Possibly making us sick? Perhaps the single biggest crutch our success rests upon is the sheer complexity and efficiency of our cells, all working together to keep us alive and smart enough to know that ‘cells’ are a thing. ![]() All very impressive stuff, I’m sure everybody agrees, however, we’ve been quite favored. ![]() Between our self-awareness and the Internet, the power to wreck whole planets, opposable thumbs and all that jazz, we humans like to think of ourselves as the bee’s knees of life. ![]()
