Kingdoms
|
Animalia, Plantae, protists, fungi, monera. Last three studies by micro.
|
|
|
Monera
|
Bacteria, archea(prokaryotes), eukarya
|
|
|
Light Microscope
|
May requirer staining and may be hard to see
types: Dark field Phase contrast Flourescent microscope |
|
|
Magnification
|
emphasis on size.(Have to be improved upon)
|
|
|
Resolution
|
Ability to distinguich closely spaced objects.(Has to be improved upon)
|
|
|
Phase contrast microscope
|
distinguished btw surface features of specimen by utlizing tunneled light.
Almost 3d views |
|
|
Flourescent Microscope
|
require the specimen to be capable of emitting light following excitation by a certain wavelength of light.
|
|
|
Confocal microscopes
|
utilize a laser beam and digitilized images to proved a 2d perspective of the cell.
|
|
|
Electron Microscope
|
Magnification power- 1000X greater then light microscope. electron beams have very short wavelength. shorter the wavelength the better the magnification.
|
|
|
types of EMs
|
Transmission-->facilitates viewing of informal structures
scanning-->surface view. |
|
|
Scanning probe microscope
|
utlizes an electrical current.(tunneling current) can see individual atoms and proteins on a cell.
