Question

Which of the following does not have a nucleus?

• A. Skin cell
• B. Human RBC
• C. Plant cell
• D. Amoeba

Answer 1

The correct option is B

Human RBC

The nucleus is the most important organelle of a typical eukaryotic cell. However, the red blood cell in human beings is an exception in this regard. Since the most important role of the RBCs is to carry oxygen (through the haemoglobin in them) around, these cells even lack a nucleus and a few other organelles, so that there is enough room for haemoglobin. All the other cells mentioned in the options have a nucleus in them.
