Unformatted text preview: Multi-Kingdom Classification Plantae Fungi Animalia Protista Archaebacteria/Eubacteria Scheme is based on 3 levels of organization 1. Prokaryotic vs. Eukaryotic 2. Unicellular vs. Multicellular 3. Types of Nutrition • Photosynthetic (plants) absorptive (fungi) Ingestive (animals ) Kingdom Monera = prokaryotes Bacteria and Blue-green Algae • Simplest organisms • Smallest (1-10 um) • Oldest (3.7 bya) • Originated in anaerobic environment ( Blue-greens caused the O2 Revolution) • Complex biochemistry • Great diversity • Enormous numbers • Both helpful and harmful to humans • Ubiquitous Eubacterium Nutrition primarily N 2 Fixation N 2 + 6H 2NH 3 used in synthesis of proteins and nucleic acids Anaerobic Process = Where does N 2 fixation occur? • Atmosphere through lightening • Fertilizer companies • Blue green Algae • Some bacteria can be free living or symbiotic Classification -Bacterial Kingdoms 1. Kingdom Archeobactria • Halophiles • Thermophiles • Methanogens 1. Kingdom Eubacteria • Decomposing bacteria • Photosynthetic bacteria • N2 fixing bacteria • Cyanobacteria = blue-green algae Binary Fission Genetic Recombination Process of conjugation F+ pilus F- donor recipient Plasmid = extra- chromosomal DNA F+ F+ F- Transduction Transformation Strategies for energy capture.
