Document Summary

The first cells that appeared were bacteria and prokaryotes. World was first divided into the 5 kingdoms by linnaeus. They classified them whether they had a nucleus or not and (prokaryotes and. Eukaryotes) based on that, prokaryotes are thought to come first because they were simpler. Differences between the plantae, fungi, and animalia kingdoms: The first organisms were heterotrophs because the oceans are full of nutrients. E. coli 0157h7 (the number/letter series is put because there are different strains of this bacteria. Also, it gives the proteins which in some cases identifies whether the strain is dangerous or harmless) The greater the surface are the faster the interchange of things that go in and out. How much can be stored on the inside compared to the outside. Bacteria have ideal surface to volume ratio so there is no need for them to have complexity in their structures from the storage point of view.
