This Catalyst article explores the complex structure of cells, and numerous theories of how they were formed. It describes how the development of electron microscopes has allowed greater detail of cellular strutures and organelles to be understood. The article includes detailed electron micropgraphs, along with descriptions of the structures that can be seen. It concludes by considering the 'endosymbiont’ theory. This suggests that complex eukaryotic cells evolved by incorporating mitochondria and plastids, such as chloroplasts and the basal bodies of flagellae, which were originally free-living bacteria.
