i was and apparently they aren't anymore. this makes me feel sad lol
or well apparently it depends on the definition and there appear to be all sorts of different phylogenetic systems?? so maybe the whittaker model is still being taught in the us i'm not sure
but apparently the most common definition now is any unicellular eukaryote. so i guess that means the closest equivalent is the kingdom Protozoa but that also either exists or doesn't depending on the classification scheme so idk!
also apparently brits teach a system that includes the kingdom of Monera and i have never heard of that in my life. that appears to be the equivalent of Archaebacteria and Eubacteria??
