Summary
This document explores the diversification of microbes, including protists, archaea, and bacteria. It covers various aspects of these biological entities, such as their roles, distributions, and classifications, along with their impact within the wider ecological context. Diagrams and other visual aids are used for detailed explanations.

Microbe Diversification Levels of Biological Organization ❊ What is a Microbe? ❊ Importance of Protist ❊ Importance of Archaea ❊ Importance of Bacteria Diversification Diversification Diversification ❊ What is a Protist? ❊ What is Archaea? ❊ What is a Bacteria? ❊ Three General Categories ❊ Adaptive Traits ❊ Classification/Identification Microbes Tiny organisms that cannot be seen with the naked eye; Too small to see with magnification. Genetically diverse Live in almost every habitat on earth and eat almost anything Abundant Organization of Life – Classification of Species Importance of Understanding Protist Diversification Oxygen source Food Source Produce ½ of earth’s oxygen! Scientific/Medical Research Nutrient Cycling & Biotransformation Protist Members of the kingdom Protista and includes all the singled-celled eukaryotes. Characteristics to Define a Protist Most are unicellular Have nucleus and organelles Protist – 3 General Categories (however, there are 6 major lineages) Animal-Like Mobile via cilia Appear to hunt for prey Example: Paramecium Fungi-Like Heterotrophic Establishes sheet-like colonies of cells Reproduce via spores Example: Slime mold https://youtu.be/HyzT5b0tNtk?si=C1J7tR3gmk20oHqW Plant-Like Grow in water Use photosynthesis Example: algae/seaweed Organization of Life – Classification of Species Importance of Understanding Archaea Diversification Biotechnology Digestion Amplify the Gene of Interest Environmental Sustainability Nutrient/Chemical Cycling Archaea A group of prokaryotes that are evolutionary distinct from bacteria and thrive in some of the most extreme environments on earth (aka extremophiles). Types (Adaptive and Unique Traits) 1. Thermophile 2. Psychrophile 3. Halophiles 4. Acidophile Organization of Life – Classification of Species Importance of Understanding Bacteria Diversification Food Biotechnology Environmental Sustainability Physical well-being Vaccines and Drugs Nutrient/Chemical Cycling Data suggests that is supports mental well-being too! Bacteria A member of a large group of unicellular microorganism which have cell walls but lack organelles and nucleus; prokaryote. May be the most diverse of all organisms (~1300 phyla)! Adaptive Traits Capsule 2 types of genetic information Rapid reproducer Bacteria – Classification by Shape Bacteria – Classification by Metabolism Chemoorganotroph Chemolithotroph Metabolism Metabolism similar to cellular similar to cellular respiration respiration but Fermentation uses inorganic Example: E. coli molecules Photoautotrophs Metabolism photosynthesis Example: Cyanobacteria Resembles 1st photosynthetic organisms from ~2.6 billion years ago Responsible for the Oxygen Revolution Accumulation of oxygen released into atmosphere Bacteria – Identification Appearance Gram Staining Technique Common and quick test to identify and diagnose bacterial infections in humans Staining the glycoprotein in cell wall Gram +: Thick; purple in color Example: Strep throat Gram -: Thin; pink in color Example: Urinary tract infections (UTI)
