- AI - A, II - B, III - C, IV - D
- BI - A, II - B, III - D, IV - C
- CI - B, II - A, III - C, IV - DCorrect
- DI - B, II - A, III - D, IV – C
Explanation
The correct option is C because it correctly matches the physiological functions with their specific cellular sites:
1. Photosynthesis occurs in the Chloroplast. Chloroplasts contain chlorophyll which captures solar energy to convert water and carbon dioxide into food.
2. Mineral uptake occurs through the Plasma membrane. The membrane acts as a selective barrier that regulates the entry of minerals and nutrients from the external environment into the cell.
3. Respiration occurs in the Mitochondria. Often called the powerhouse of the cell, mitochondria are responsible for cellular respiration and the production of energy in the form of ATP.
4. Protein Synthesis occurs in the Ribosomes. Ribosomes are the cellular structures where genetic code is translated into polypeptide chains to form proteins.
Therefore, the correct sequence is I-B, II-A, III-C, and IV-D.
