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.

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. 5-6
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.
Repeat the same process for Chapter 7-fungus Fig. 7-7

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
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?
