Study Set Content:
Uses laser scanning microscope utilizes an optical imaging technique. This is used together with computers
and is useful in the study of cell physiology.
Confocal
higher resolving power than compound light microscopes.
Electron
Enable us to see extremely small microbes such as rabies and smallpox viruses
Electron
An electred as the source of illumination, and magnets are used to focus the beam
Electron
Two types of electron
Transmission and scanning
uses an electron gun to fire a beam
of electrons through an extremely
thin specimen (
Transmission
electrons are bounced off the surface
of a specimen and the image appears
on a monitor.
Scanning
An image of the specimen is
produced on a phosphor-coated
screen
Transmission
Magnification is approximately 1,000
times greater than with the
compound light microscope.
Transmission
this is used to observe the outer
surfaces of specimens.
Scanning
resolving power of this microscope is
about 100 times less than that of
transmission electron microscope.
Scanning
Uses a thin metal probe that scans a
specimen
Scanning tunneling
Uses a metal & diamond probe gently
forced down along the surface of the
specimen.
Atomic force
Provides very detailed views of
molecules inside cells
Scanning tunneling
Provides images of biological
molecules in nearly atomic detail &
molecular processes.
Atomic force
Multicellular
Molds
Simplest form of fungi
Yeasts
Budding cells: reproduction
Yeasts
Can develop tiny spores that ride in the air & spread by air currents
Molds
Prefer neutral pH
Molds
