---|---|
Bacteria | First to appear on earth Over 4,000 species of bacteria today Some cause diseases (typhoid,strep-throat) Some are useful (fermentation,other foods) |
Protists | Outweigh other microbes due to their genetic codes being packed into the nucleus 200,000 species organized into 3 specific groups Algae-make their own food through photosynthesis,Protozoa-hunt for food,Slime Mold-can hunt,or cover themselves with slime |
Fungi | Absorb nutrients from dead or decaying life forms Has a nucleus More than 100,000 species Most common are mushrooms,yeast,mold,and mildew Easy to see because they form clusters of one-celled organisms |
Viruses | Viruses make you sick They can't stay alive on their own-need a host The simplest of all microbes The capture other cells and inject their genetic codes which forces those cells to create and feed new viruses Medicines usually can't treat a virus |
