  1. Classification of Prokaryotes
    • Prokaryotic species: A population of
    • cells with similar characteristics

    • Culture
    • Grown in laboratory media

    • Clone
    • Population of cells derived from a single
    • cell

    • Strain
    • Genetically different cells within a
    • clone
  2. classification of eukaryotes
    • Eukaryotic species: A group of closely
    • related organisms that breed among themselves

    • Animalia:
    • Multicellular
    • No cell walls
    • Chemoheterotrophic – an organism that uses
    • organic molecules as a source of carbon and energy


    • Plantae:
    • Multicellular
    • Cellulose cell walls
    • Usually photoautotrophic – Organism that
    • uses light as its energy source and carbon dioxide as its carbon source

    • ØFungi:
    • Absorptive Chemoheterotrophic – Chemoheterotroph is an organism that uses organic molecules as a source of carbon and energy
    • Unicellular or multicellular
    • Cell walls of chitin
    • Develop from spores or hyphal
    • fragments



    • ØProtista:
    • A catchall kingdom for eukaryotic organisms that do not fit other kingdoms
    • Grouped into clades based on rRNA 
    • Still being assigned to Kingdoms
    • CLADES = GROUP OF ORGANISMS THAT SHARE A COMMON ANCESTOR  (CLAYD)
  3. Classification of viruses
    Not placed in a Kingdom

    Not composed of cells and cannot grow without a host cell


    • VIRAL SPECIES
    • Population
    • of viruses with similar characteristics that occupies a particular ecological niche
  4. Alphaproteobacteria
    • Wolbachia:
    • Live in insects and other animals



    • May be the most common infectious
    • bacterial genus on earth



    • Infects over a million species of insects
    • & other vertebrates



    • Cell of a fruit fly embryo infected with Wolbachia
    • (red)
