Question:
Which one of the following is a membrane-less structure?
Which one of the following is a membrane-less structure?
Show Hint
Ribosomes, Nucleolus, and Centrosomes are the major membrane-less components of the cell.
Updated On: May 14, 2026
- Centrosome
- Cytochrome
- Endosome
- Peroxisome
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Cell organelles are either double-membrane bound (mitochondria), single-membrane bound (lysosomes), or membrane-less.
Step 2: Analysis
Endosomes and peroxisomes are single-membrane bound vesicles. Cytochromes are proteins, not organelles.
Step 3: Identification
The centrosome (containing centrioles) is a specialized structure involved in cell division that does not possess a limiting membrane.
Step 4: Conclusion
The centrosome is the membrane-less structure. Final Answer: (A)
