Anton Van Leeuwenhoek (1632-1723)
Leeuwenhoek also called bacteria and protozoa as _______.
animalcules
On/Off Switch Location
At the side of the base
Stage Location
Beneath the nosepiece and the objective lenses.
Condenser Control Knob Location
Beneath and behind the condenser
A type of microscope characterized by:
- fluorescent dye attached to organism
- immunodiagnostic technique
- used to detect microbes
Fluorescence Microscope
It supports the binocular body and the revolving nosepiece.
Arm
An optical instrument that is used to observe tiny objects, often objects that cannot be seen at all with the unaided human eye.
Microscope
Objective Lens Location
Above the stage, held by the nosepiece
A flat surface on which the specimen is placed.
Stage
Revolving Nosepiece Location
Above the stage
Condenser Location
Beneath the stage
It adjusts the height of the condenser.
Condenser Control Knob
This is used to observe the morphology of the specimen in living and non-living state.
Brightfield Microscope
Ocular Lens (Eyepiece) Location
At the top of the microscope
Rheostat Control Knob Location
At the front side of the base
Leeuwenhoek is the Father of __________.
Microbiology, Bacteriology, and Protozoology
It holds the ocular lenses.
Binocular Body
It controls the amount of light emitted from the light source.
Rheostat Control Knob
Field Diaphragm Lever Location
Attached to the field diaphragm
It turns the light source on and off.
On/off Switch
This is used to observe unstained microorganisms, and is useful in examining thin spirochetes.
Darkfield Microscope
It adjusts the amount of light passing through the collector lens.
Field Diaphragm Lever
This is where the observer looks to view the specimen.
Ocular Lens (Eyepiece)
It magnifies the specimen placed on the stage.
Objective lenses
What did Anton Van Leeuwenhoek saw under the microscope?
Bacteria and Protozoa
It controls the amount of light entering the condenser.
Collector Lens with Field Diaphragm
Stage Adjustment Knob Location
Beneath the stage
It adjusts the amount of light passing through the condenser.
Iris Diaphragm Control Arm
This is used to observe unstained living microorganisms.
Phase-contrast Microscope
It contains a lens system that focuses light onto the specimen.
Condenser
It moves the stage and the microscope slide.
Stage Adjustment Knob
Iris Diaphragm Control Arm Location
On the condenser
It contains the light source.
