					                                          • The grouping of organisms into
                                            kingdoms is based on 3 factors:
        6 Kingdoms of Life
                                            1. Cell Type
                                            2. Cell Number
                                            3. Feeding Type




                                                      Prokaryotes
1. Cell Type- The presence or absence
  of cellular structures such as the
  nucleus, mitochondria, or a cell wall   • DO NOT HAVE:
    Prokaryotes & Eukaryotes                 •a membrane bound
                                             nucleus

                                             organelles




          …Prokaryotes


• DO HAVE:
  • DNA
  • Ribosomes
  • Cytoplasm
  • Cell
  membrane
             Eukaryotes

• DO HAVE:
     • separate membrane bound
       nucleus
     • other organelles




2. Cell #
Whether the organisms exist as single cells
or as many cells                                     3. Feeding Type - How the organisms
                                                       get their food
     •Unicellular- single celled organism
     •Multicellular- many celled organism           Autotroph (producer)
                                                      •Makes it’s own food


                                                    Heterotroph (consumer)
                                                      •Must eat other organisms to survive

 •Vascular plants have water-carrying tissues
 (xylem) and sugar-carrying tissues (phloem)
 enabling the plants to evolve to a larger size.

 •Vascular plants produce seeds.

•  The viral reproductive process includes     Viruses are transmitted through vectors,
   the following steps:                          such as:
1. A virus must insert its genetic material    • Airborne
   into the host cell.                           – Influenza
2. The viral genetic material takes control      – Common cold
   of the host cell and uses it to produce
   viruses.
3. The newly formed viruses are released
   from the host cell.
                  Virus Vectors                                 Virus Vectors

– Viruses cannot be treated with antibiotics.     adorette/taxomy/6kingol.ppt

– There are some anti-viral drugs available.

– You generally have to wait for the virus to
  run its course and let your immune system
  fight it off.
