Prokaryotes: Bacteria and Archaea
Powerpoint Lecture
The exact mechanism that lead to the emergence of the first prokaryotic life is unknown.This lecture begins with some of the big experiments, such as the Miller-Urey apparatus. An anatomical diagram of a typical bacterium is covered, followed by an overview of some common species of both archaea and bacteria. Students will learn the difference between autotrophs and heterotrophs, as well as anaerobes and aerobes. The relationship humans have with bacteria, both parasitic and beneficial, is also explored.
Essential concepts: Miller-urey apparatus, bacteria, archaea, prokaryotes, autotroph, heterotroph, aerobes, anaerobes, extremophiles, thermophiles, halophiles, methanogens, binary fission, exponential growth, coccus, bacillus, spirilla, flagella, symbiosis, mutualism, commensalism, parasitism, decomposers, antibiotics.
