2.3 More Microscopy

Question 1

Electron microscopy

Answer 1

Beams of electrons used to illuminate specimen. Much more detail

Question 2

Artefact

Answer 2

Foreign structures produced due to fault in the preparation process

Question 3

Transmission electron Microscopy (TEM)

Answer 3

Beam of electrons transmitted through specimen. Best resolution

Question 4

Scanning electron Microscopy (SEM)

Answer 4

Beam of electrons sent across surface of specimen. Reflected electrons are collected. 3D images of surface are produced

Question 5

Micrograph

Answer 5

Picture taken through microscope

Question 6

Mesosome

Answer 6

Structure found in prokaryotic cell. Aid in synthesis of membrane, protein & DNA replication

Question 7

Laser scanning confocal microscope

Answer 7

Single spot of focused light moves across specimen. Causes fluorescence. Emitted light is detected and filtered through a pinhole aperture
