1. The six kingdoms are Archaebacteria,
Eubacteria, Protista, Plantae, Fungi, and
Animalia.
2. The three domains are Archaea, Bacteria,
and Eukarya.
3. Monera was divided into two kingdoms
because scientists have come to recognize
profound differences among two broad
groups of Monera.
4. Members of the kingdom Protista display
the greatest variety, sharing characteristics
with plants, fungi, or animals; protists cannot
be classified in any other group.
5. Fungi are heterotrophic; Plantae are
autotrophic. Both are nonmotile.
