Lab Safety Rules - Disinfect lab table before and after lab session with a disinfectant
known to kill the organisms handled.
Magnification/resolution - are inversely proportional. Magnification is how large an
image is. Resoloution is how clear the image is. The more magnification the more unclear it
will be.
Sub stage condenser - has a lens that concentrates and focuses light onto the subject.
Iris diaphragm - is the device that controls the amount of light going onto the object.
Total Magnification - Ocular lens (10x) x Objective Lenses (4,10,40,100)
Objective Lens (Scanning objective) - magnifies the image 4x. Total magnification would
be 40.
Objective Lens (Low power objective) - magnifies the image 10x. Total magnification
would be 100.
Objective Lens (High dry objective) - magnifies the image 40x. Total magnification
would be 400.
Objective Lens (Oil immersion objective) - magnifies the image 100x. Total
magnification would be 1000.
Paramecium - Kingdom Protista
Spirogyra - Kingdom Protista
Saccharomyces - Kingdom Fungi (purple clusters)
Streptoocci - Kingdom Monera (purple blob with clusters around edges)
Baccilus - Kingdom Monera (purple stripes on highway)
Spirilla - Kingdom Monera
Chloroplasts - are the organelles you observe when viewing the spirogyra under the
microscope. This is what gives spirogyra their GREEN color.
