Question

Quizplus · Accepted Answer

The major difference between a kingdom and a domain is that all eukarya belong to one domain, while prokaryotes are divided into two domains (Bacteria and Archaea). The concept of domains was introduced to reflect the evolutionary relationships among organisms and to reflect the differences between prokaryotic and eukaryotic cell types. Therefore, option B is the correct choice. Option A is incorrect because domains are larger categories that include kingdoms. Option C and D are incorrect because they do not accurately reflect the organization of living organisms into domains and kingdoms. Option E is incorrect because it refers to a characteristic of organisms (ability to produce their own food) rather than their classification into domains and kingdoms.
