Cell Size, Microscopes and Magnification

HideShow resource information
The degree to which it is possible to distinguish between two objects that are very close together is called...
Resolution
1 of 18
Euglena and Daphina are a type of....that can be viewed using a light Microscope
Specimen
2 of 18
This is the final image produced from an electron Microscope it is always black, white and grey but colour can be added later, ( the colour ones are called 'false-colour' electron...)
Micrographs
3 of 18
What is a micrometre
one millionth of a metre
4 of 18
Any process that helps to reveal or distinguish different features is called...
Staining
5 of 18
Uses a number of lenses to produce an image that can be viewed directly at the eyepeice
Light Microscope
6 of 18
Final Image Produced is 2 dimensional
Transmission Electron Microscope (TEM)
7 of 18
Has four objective lenses
Light Microscope
8 of 18
A specimen is embedded in wax and thin pieces are then cut without distorting the structure of the specimen
Sectioning
9 of 18
Can be used to used to produce detailed images of the structures (organelles) inside the cell
Electron Microscope
10 of 18
The final image produced is a 3D view of the surface of the sample
Scanning Electron Microscope (SEM)
11 of 18
Magnification possible is x500,000
Transmission Electron Microscope (TEM)
12 of 18
An advantage of this type of microscope is that the resolution is 0.1 nanometre (nm)
Electron Microscope
13 of 18
Some of the limitations of this microscope is that ... beams are deflected by the molecules in the air so samples have to be placed in a vaccum
Electron Microscope
14 of 18
what is a nanometre
one thousand million of a metre
15 of 18
Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM) are a type of this microscope
Electron Microscope
16 of 18
You need to have a high degree of skill and training to be able to use this type Microscope
Electron Microscope
17 of 18
A limitation of this type of microscope is that it is very expensive
