Question:
Both cell organelles namely nucleus and lysosomes are absent in ______________.
Both cell organelles namely nucleus and lysosomes are absent in ______________.
Show Hint
Absence of nucleus increases oxygen-carrying efficiency of human RBCs.
Updated On: Mar 28, 2026
- Paramoecium
- R.B.Cs. of camel
- mature human R.B.Cs.
- vertebrate liver cells
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding mature human RBCs.
Mature human red blood cells are specialized for oxygen transport.
Step 2: Structural modifications in RBCs.
During maturation, human RBCs lose their nucleus and most organelles, including lysosomes, to maximize space for haemoglobin.
Step 3: Elimination of incorrect options.
Paramoecium and liver cells possess nucleus and lysosomes.
Camel RBCs retain nucleus during certain stages.
Step 4: Conclusion.
Mature human RBCs lack both nucleus and lysosomes.
Mature human red blood cells are specialized for oxygen transport.
Step 2: Structural modifications in RBCs.
During maturation, human RBCs lose their nucleus and most organelles, including lysosomes, to maximize space for haemoglobin.
Step 3: Elimination of incorrect options.
Paramoecium and liver cells possess nucleus and lysosomes.
Camel RBCs retain nucleus during certain stages.
Step 4: Conclusion.
Mature human RBCs lack both nucleus and lysosomes.
