What is homogenation?

Select one of the following:

  • The preparation of the sample for cell fractionation

  • The breaking down of cells in a homogeniser

  • The removal of foreign objects in a sample

Question 5 of 10

1

At what speed are nuclei, mitochondria and lysosomes separated out?

Select one or more of the following:

  • Nuclei- 3500 min-1

  • Mitochondria- 16500 min-1

  • Lysosomes- 1000 min-1

  • Nuclei- 1000 min-1

Question 6 of 10

1

Transmission electron microscope (TEM)

Select one of the following:

  • A thin sample is used to create a photomicrograph-not in colour. A photomicrograph is a 2D flat image due to the thinness of the sample and it has a resolution of 0.1 nanometres.

  • Sample does not need to be too thin as electrons don't penetrate. Creates a 3D image which can be coloured and it has a resolution of 20 nanometres.
