Bacteria Bacteria are the most numerous organisms on earth Inhabit arctic and Antarctic to the bottom of the sea Primary decomposer of the world Hetero and autotrophic forms Reproduce by binary fission —1 cell splitting into 2 Can exchange genetic material—transformation & conjugation Bacteria Shapes Structure of Bacteria Cell wall and cell membrane Circular DNA Endospore protect it from harsh environments Flagella—whip like structures that aid in movement Bacteria/ Human Eubacteria cause diseases in humans by releasing toxins, and destroying body tissues—tooth decay, food poisoning, Strep Throat Antibiotics are widely used to kill bacterial infections— penicillin They are useful to help purify sewer, process many foods (yogurt, cheese, pickles) Bacteria such as E. coli help digest food, and supply vitamins Archaebacteria Archaebacteria live in harsh environments Virus Virus - a non-cellular particle made up of genetic material and protein that can invade living cells. *** Viruses cannot carry out any life processes unless they are within a living host cell.
