1.2. Cell Biology And Microscopy Flashcards
One of the methods cell biologists use to study cells is
using various types of microscpe
The two fundamentally different types of microscopes are
Light microscope and electron microscope
The light microscope and the electron microscope use a form of _____ in order to see the specimen
Radiation
The light microscopes uses light as a form of radiation while the electron microscope uses electrons.
The smallest structure visible to the human eye is
50–100 µm in diameter (roughly the diameter of a sharp end of a pin)
The cells in your body vary in size from about
5 µm to 40 µm
Average bacterial cell is
About 1 µm across
One of the smallest structures in the syllabus is
Ribosome, which is only about 25 nm in diameter
1mm equals to
1000 micrometer
1 micrometer equals to
1 nm
