What is a microorganism (microbe)? -microscopic unicellular organisms -not just bacterial -exist in all 3 domains (eukaryotic, bacteria, archaea) -viruses also considered microbes eukaryotes -protists and fungi -extensive membrane-bound organelles -DNA enclosed in a membrane-bound nucleus -cells are generally larger and more complex -18S rRNA Prokaryotes -bacteria and archaea -no extensive membraine bound organellses (but some bacteria still have membrane bound organelles) -no nucleus -diverse...

Microbes Microscopic single-cell organisms Can exist as a single cell or in various types of colonies or multi-cellular formations that exhibit cellular differentiation - Self-replicating bioconversion machines - drivers of many chemical conversions Why is genetic diversity important? Genetic diversity-->gene diversity-->enzyme diversity-->biochemical diversity-->biological funciton diversity Enzyme biological catalyst - lowers activation energy - not modified as a result of the re...
