Document Summary

Arrival of the single celled eukaryotes - the protists. The available: introduction, eukaryote endosymbiosis,viruses, prions and viroids, (show me all this on one page). following topics are origins, evidence for. An updated version of parts of this document appear in. Eukaryotes differ from their prokaryote counterparts in a number of ways, not the least of which is size. Along with an increase is size is an increase in cellular complexity including an elaborate internal membranes the endomembrane system. Cells exchange materials with their external environment bringing in nutrients and carbon dioxide if they are plants, or oxygen of they are animals or fungi, across their plasma membrane the interface with the external environment. They also remove wastes across the same surface. Cellular function occurs in the volume of the cell and the relationship between supply (surface) and function (volume) is referred to the surface:volume ratio for the cell.
