MICROORGANISMS

IDENTIFYING MICROORGANISMS � You will need to go to a station 1, 2, and 3. � Take your toolkit with you to record in. � Once at a microscope use only the FINE adjustment knob if you need to focus. � Draw your field of view, title your drawing and label it with the total magnification. � Identify the type of microorganism.

TEXTBOOK INTERACTION � � � � � Open text to Chapter 5 Read intro page (Monerans just a fancy word for bacteria) Look at all the pictures and diagrams, read the captions Skim the reading Find the diagram of the virus (also called bacteriophage) Fig. 56 Find the diagram of the bacteria Fig. 5 -12 (Title the next page in your Toolkit: Microorganisms) Draw-(do not trace!) the virus and bacteria diagrams on this page in your Toolkit, under each flipper. Label all the structures from the diagram and color your diagram.

BACTERIA

BACTERIA http: //photos 1. blogger. com/x/blogger/1918/602/1600/773294/bacteria 1. jpg http: //www. sciencehound. com/science_project_community/images/e 3 abd 7548047454 dd 2154113 c 0 e 133 ce 5333. gif

BACTERIA � One celled organism � No nucleus, so genetic material freely floats in cytoplasm � May be good or bad � Must have bacteria in digestive tract � Decomposer, cause illness like T. B. and other infections � Grows in colonies, usually circular or lines

VIRUSES

VIRUS LIFE CYCLE http: //users. rcn. com/jkimball. ma. ultranet/Biology. Pages/V/Viruses. html Develop a short skit, song, reading, poem, Something to show your team’s understanding of the life cycle of a virus.

VIRUSES � Alive or not? Can NOT reproduce without a host cell. � Can NOT be seen with a compound microscope, must use electron microscope � Takes over living cells and multiplies like crazy then blows up cell, more viruses go do the same thing � Disease Causing � Ex: Cold, flu, HIV, warts, coldsores

FUNGI

FUNGUS � Decomposers that live off other organisms, usually dead organisms � most are “fuzzy” � Ex: molds, yeast, mushrooms, athlete’s foot, and ringworm

CAN YOU FIND THE BACTERIA IN THIS FUNGUS?
