Which of the following is true about eukaryotic cells?

• A. They all contain a plasma membrane, a cell wall, and divide through mitosis
• B. They all contain a plasma membrane, store their DNA in a nucleus, and have membrane bound organelles
• C. They all contain a plasma membrane, have cytoskeletal elements, and do not contain a nucleus
• D. They all contain a plasma membrane, divide through mitosis, and do not contain a nucleus

Answer: (B)

Verified step by step guidance

1. Identify the key characteristics of eukaryotic cells: Eukaryotic cells are defined by having a plasma membrane, storing their DNA in a nucleus, and possessing membrane-bound organelles.
2. Evaluate the first option: While eukaryotic cells do have a plasma membrane and can divide through mitosis, not all eukaryotic cells have a cell wall. For example, animal cells lack a cell wall.
3. Evaluate the second option: This option states that eukaryotic cells have a plasma membrane, store their DNA in a nucleus, and have membrane-bound organelles, which are all true characteristics of eukaryotic cells.
4. Evaluate the third option: Although eukaryotic cells have a plasma membrane and cytoskeletal elements, they do contain a nucleus, which contradicts this option.
5. Evaluate the fourth option: This option is incorrect because eukaryotic cells do contain a nucleus, which is a defining feature of eukaryotic cells.
