Which term refers to organisms that have no nucleus, such as bacteria?

Explanation:
Organisms without a nucleus are prokaryotes. In prokaryotic cells, DNA is not enclosed by a membrane-bound nucleus; it typically resides in a region called the nucleoid, and the cell lacks most of the internal membrane-bound organelles found in more complex cells. This distinguishes them from eukaryotes, which have a true nucleus and organized internal membranes. The other terms describe metabolic requirements related to oxygen (aerobic uses oxygen, anaerobic does not) and do not address the presence or absence of a nucleus, so they don’t identify the cell’s basic organization. Therefore, the term that fits organisms like bacteria is prokaryote.
