Question

Identify the functions not related to Cytoskeleton?
I. Mechanical support
II. Cell motility
III. Intercellular transport
IV. Mesosome formation

• A. I & II
• B. I & III
• C. II & III
• D. III & IV

Hint:

Read the question carefully: it asks for functions {NOT related}.

Answer 1

The Correct Option is D

Step 1: Analyze Cytoskeleton Functions:
The cytoskeleton is an elaborate network of filamentous proteinaceous structures in the cytoplasm. Its main functions are:

• Mechanical support: Yes (I).
• Motility: Yes (II) (e.g., cilia, flagella, amoeboid movement).
• Maintenance of shape: Yes.

Step 2: Analyze Non-Functions:

• III. Intercellular transport: The cytoskeleton helps in \intracellular transport (within the cell). \Intercellular transport (between cells) is primarily facilitated by plasmodesmata and vascular tissue, not the cytoskeleton directly.
• IV. Mesosome formation: Mesosomes are infoldings of the plasma membrane found in prokaryotes (bacteria). The cytoskeleton (microtubules, etc.) is a characteristic of eukaryotes.

Step 3: Conclusion:
Functions III and IV are not related to the cytoskeleton.
