Question:
Mature human RBCs are
Mature human RBCs are
Show Hint
Mature red cells lose their nucleus and have a disc shape thinner in the middle.
Updated On: Nov 12, 2026
- Nucleated and biconvex
- Non nucleated and biconcave
- Nucleated and circular
- Non nucleated and oval
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Red blood cells carry oxygen using haemoglobin.
Step 2: Recall features
Mature human RBCs lose their nucleus, giving more room for haemoglobin.\nThey are discs thinner at the centre, that is biconcave.
Step 3: Conclusion
They are non-nucleated and biconcave.
Final Answer:
Mature human RBCs are non-nucleated and biconcave. \[ \boxed{\text{(B) }\text{Non nucleated and biconcave}} \]
