  1. 1. Values are expressed as the mean number of gold particles per μm2± SE; 2. n = number of observations
  2. 3. Different letters indicate significant differences in the density of gold particles between the protoplasm and the vacuole at the 0.05 significance level based on the Duncan’s Multiple Range Test.
