  • How did cell densities of stationary phase cultures compare with those of log phase cultures? Propose an explanation for any differences that you noted.

    An investigator spots two different strains of S. cerevisiae on a YPD plate. Both strains have the same number of colonies in each dilution, but the colonies from one strain are much smaller than those of the other strain. Propose an explanation for these results.
