Plants, People and the Environment
Lecture 2. The wee ones: Archaebacteria, Eubacteria, and Protista.
Some people think that life on other planets may resemble our procaryotes in Kingdoms Archaeabacteria and Eubacteria. These two links give you more information about bacteria: The microbe zoo (There's some really neat graphics and information at this site!) and What is Life? by Bryce Klyce (Nice graphics).
For information about Archaebacteria see: Introduction to the Archaea. To see how a virus can infect a bacterium, look at the Bacteriophage graphics at this site.
To find out more about the idea the life might have originated in outer space, follow this link about Panspermia: The modern version of Panspermia. Disclaimer: I'm including this link just because there's a lot of good information about bacteria -- not that I'm advocating support for this hypothesis. If you are interested in reading more about the origin of life and the debate surrounding origins, check out the links for my Plant Biology 694 course (Creation and Evolution: Differing World Views).
If you are interested in the role bacteria, viruses and fungi play in infectious diseases, check out this site: Infectious Diseases. To see how these microscopic agents can be used in biological warfare, here are two sites that summarize the dangerous use of microbes: Iraq's Bioweapons: Easy to Make, Easy to Hide and Accelarated Anthrax Vaccination Program.
For information about disease organisms, check out Bugs in the News and Bubonic Plague.
Here are some good sites that have a lot of information and/or pictures for organisms in Kingdom Protista. First of all, there is the Protists Picture Gallery.
For diatoms: Diatoms: Nature's Marbles and Diatoms of the Great Lakes.
For dinoflagellates: Dinoflagellates, Grass of the Sea: The Dinoflagellates, and About Red Tides.
For slime molds: Introduction to the Slime Molds. This is a great site - check it out!
