There is no way yeast could be 120 um in size. 120um = .12 mm!
You could see a single yeast cell with the naked eye if this were true. I
think 3-5 um is more reasonable. I routinely size yeast on a Coulter
counter and the avg diameter (of a sphere representing the volume of the
cell) comes out around 3 um for haploid strains.
