Correct Statements Explained
The correct answer is option 'A' because statements ii and iv are accurate regarding the photosynthetic process and its environmental interactions.
Statement i: Water's Role in Photosynthesis
- Water is crucial for photosynthesis, specifically during the light reactions. It provides electrons and protons, which are essential in the conversion of light energy into chemical energy. Therefore, statement i is correct.
Statement ii: Water Stress and Wilting
- Water stress can cause wilting of leaves. When a plant lacks sufficient water, it may close its stomata to prevent water loss, which reduces the surface area available for gas exchange and photosynthesis. This statement is correct.
Statement iii: C3 vs. C4 Plants
- C3 plants generally prefer cooler temperatures for optimal photosynthesis, while C4 plants are better adapted to high temperatures. Therefore, statement iii is incorrect as it inaccurately compares the temperature optima of C3 and C4 plants.
Statement iv: Temperature Effects on Photosynthesis
- The effect of temperature on photosynthesis indeed varies depending on the plant’s habitat. Different species have adapted to thrive in specific temperature ranges, which affects their photosynthetic efficiency. This statement is correct.
Conclusion
- Hence, the accurate statements are ii and iv, making option 'A' the correct choice.

- Statement i is incorrect; while water is a reactant in the light reactions, its effect is more indirect through its role in plant health and stomatal function.
- Statement ii is correct; water stress leads to wilting, which reduces leaf surface area and consequently metabolic activity.
- Statement iii is incorrect; C3 plants generally have a lower temperature optimum compared to C4 plants.
- Statement iv is correct; different plants have different temperature optima based on their habitats.
Thus, the correct statements are ii and iv.
