Final answer:
The prokaryotic domains are Bacteria and Archaea, which consist of unicellular organisms without a nucleus, whereas Eukarya consists of organisms with nucleated cells.
Step-by-step explanation:
The domains that consist of prokaryotes are Bacteria and Archaea. These two domains include unicellular organisms that lack a nucleus and other membrane-bound organelles. In contrast, the domain Eukarya comprises organisms with cells that have a nucleus, including plants, animals, fungi, and protists.
It is important to note that the domain Archaea consists of single-cell organisms that often inhabit extreme environments and have unique characteristics that distinguish them from Bacteria. Both Archaea and Bacteria are essential to life on Earth, with roles in various ecological processes and environments.
