Question map
Match List I (Physiological processes) with List II (Cell organelles) and select the correct answer by using the codes given below the lists
List I | List II
I. Photosynthesis | (A) Plasma membrane
II. Mineral uptake | (B) Chloroplast
III. Respiration | (C) Mitochondria
IV. Protein Synthesis | (D) Ribosomes
Explanation
The correct answer is Option 3 (I - B, II - A, III - C, IV - D) based on the specific functional roles of cellular organelles:
- I - B (Photosynthesis - Chloroplast): Chloroplasts contain chlorophyll and are the primary sites for photosynthesis in plant cells, converting light energy into chemical energy.
- II - A (Mineral uptake - Plasma membrane): The plasma membrane acts as a selective barrier. Mineral uptake occurs through this membrane via active or passive transport mechanisms (ion channels and carriers).
- III - C (Respiration - Mitochondria): Known as the "powerhouse of the cell," mitochondria are responsible for aerobic respiration and the production of ATP.
- IV - D (Protein Synthesis - Ribosomes): Ribosomes are the cellular machinery where translation occurs, decoding mRNA to synthesize polypeptide chains.
Options 1 and 2 are incorrect as they associate photosynthesis with the plasma membrane. Option 4 is incorrect because it wrongly pairs respiration with ribosomes and protein synthesis with mitochondria.
