A comparative study of microbial size

Q1. In animal cells and in the meristem cells of land plants the nuclear envelope disintegrates during mitosis. This disintegration does not occur in the cells of most protests and fungi. According to our current knowledge of plant evolution, which group of organisms should feature mitosis most similar to that of land plants.

Q2. A comparative study of microbial size, using a stage micrometer, requires that you measure Bacillus subtilis in both the stained and unstained states. Would you expect measurements to be comparable in both preparations? If a variation in size is expected, how would you account for this difference?
