Question

Match List - I with List - II. 

Choose the correct answer from the options given below : 
 

• A. A-IV, B-III, C-I, D-II
• B. A-III, B-IV, C-II, D-I
• C. A-II, B-III, C-IV, D-I
• D. A-III, B-II, C-I, D-IV

Hint:

Organelle functions are standard textbook biology. Always match the easiest, most iconic pair first (e.g., Mitochondria = ATP). Here, identifying A = IV instantly eliminates options B, C, and D, saving valuable time during the exam!

Answer 1

The Correct Option is A

Step 1: Concept:
The question requires matching fundamental cellular organelles and structural components with their primary physiological functions.

Step 2: Step-by-step Explanation:

• A. Mitochondria: Universally known as the "powerhouse of the cell," the primary function of mitochondria is oxidative phosphorylation, producing the cell's vital energy currency. Therefore, its function is Energy generation by ATP synthesis.
Thus, A matches with IV.

• B. Cytoskeleton: This is a dynamic network of interlinking protein filaments (microtubules, actin filaments, intermediate filaments) present in the cytoplasm. It acts like a cellular scaffold, providing structural Shape and support to the cell.
Thus, B matches with III.

• C. Lysosomes: These are membrane-bound organelles containing an array of acidic hydrolytic enzymes. They function as the cell's waste disposal system, digesting obsolete components and participating in the Breakdown of macromolecules for catabolism.
Thus, C matches with I.

• D. Ribosomes: Composed of RNA and proteins, these macromolecular machines translate messenger RNA (mRNA) into amino acid chains. They are the Main site for synthesis of new proteins or polypeptides.
Thus, D matches with II.

• Putting it together: A-IV, B-III, C-I, D-II.

Step 3: Final Answer:
The matching pairs correspond to Option (A).
