  2. What is a Micro-Organism? • An living organism that is too small to be seen with the naked eye. • Also known as “microbes”. • They are found everywhere in the world. • You need a microscope to see them. • There are many different types of microorganisms including: - bacteria -fungi -viruses -algae http://www.pbs.org/strangedays/glossary/M.html http://library.thinkquest.org/CR0212089/micr.htm

  3. What do Micro-Organisms Do? • Micro-Organisms do just about anything, but most are responsible for breaking things down. • Some cause diseases (bacteria, viruses, fungi). • Some break down soil into food for plants to absorb. • Some are used in medicine to help cure diseases. http://www.biology4kids.com/files/micro_bacteria.html http://library.thinkquest.org/CR0212089/micr.htm

  4. Bacteria • Single-celled. • Reproduce through Asexual reproduction. • Live everywhere. • Can live in extremely hot and extremely cold temperatures. • Can cause food poisoning, acne, and cavities. • Help waste decompose, make oxygen, and break down food. http://www.lessonplanspage.com/SciencePEBacteriaFriendOrFoeAndProperHandWashing45.htm

  5. Fungi • Mushrooms, rust and yeast are examples of fungi. • Can be uni-cellular or multi-cellular. • Reproduce through sexual reproduction. • Fungi break down dead and organic matter into nutrients to be absorbed by plants. http://tolweb.org/Fungi http://library.thinkquest.org/CR0212089/fungi.htm

  6. Viruses • Cause infectious diseases. • Replicates in the cells of another organism. • Have genes made of DNA and RNA. • Millions of different types of viruses. • Infect both plants and animals. • Smaller than bacteria. http://www.news-medical.net/health/What-is-a-Virus.aspx http://www.medterms.com/script/main/art.asp?articlekey=5997
