What term describes organisms with cells that contain a nucleus?

• A. Eukaryote
• B. Prokaryote
• C. Classification
• D. Branching tree diagram

Answer: (A)

Organisms with cells that contain a nucleus are eukaryotes. In a eukaryotic cell, the DNA is enclosed within a membrane‑bound nucleus that houses and protects genetic material, and the cell typically contains other specialized organelles like mitochondria and, in plants and some algae, chloroplasts. This setup contrasts with prokaryotes, whose DNA floats in a region that isn’t enclosed by a membrane and who lack a true nucleus. Examples of eukaryotes include plants, animals, fungi, and many protists. The term eukaryote comes from Greek roots meaning “true nucleus.” The other terms describe processes or diagrams rather than a cellular feature, so they don’t describe the type of cell.
