Which term describes organisms with cells that contain a nucleus?

• A. Eukaryote
• B. Prokaryote
• C. Shared derived characteristics
• D. Branching tree diagram

Answer: (A)

The main idea here is about what kind of cell organization governs the classification term. Organisms that have cells with a nucleus enclosed by a membrane contain their DNA inside that nucleus and typically have other membrane-bound organelles. This distinguishes them from cells that lack a true nucleus. That’s why the correct term is eukaryote. It specifically describes organisms whose cells have a membrane-bound nucleus, such as plants, animals, fungi, and many protists. The other options aren’t describing this cell feature: prokaryote refers to organisms whose cells do not have a membrane-bound nucleus; shared derived characteristics are traits used to compare evolutionary relationships; and a branching tree diagram is a graphic tool to show how species are related, not a name for organisms with nuclei.
