Question

What major characteristics distinguishes eubacteria from protistans?

Answer 1

The major difference is that the eubacteria (monera) are prokaryotic (no nuclei or membrane bound organelles), whereas the protista are eukaryotic (nuclei and membrane bound organelles). Eubacteria tend to stain either gram negative or gram positive, whereas the protista do not.
