Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Historical discoveries in photosynthesis.
Step 2: Analysis
(I) Joseph Priestley discovered that green plants evolve oxygen (D). (II) T.W. Engelmann described the first action spectra of photosynthesis (E). (III) Julius von Sachs provided evidence that the green parts of the plant produce glucose (A). (IV) Jan Ingenhousz showed that light is required for photosynthesis (B).
Step 3: Conclusion
The correct matching is I-D, II-E, III-A, IV-B.

- The reaction that does not contribute for proton gradient across thylakoid membrane.
- Assertion (A): Photorespiration is a wasteful process.
Reason (R): There is no synthesis of sugars, ATP or NADPH, instead ATP is utilized and CO$_2$ is released in photorespiration. - Assertion (A): C\(_4\) plant loses only half of the water compared to C\(_3\) plant for the same amount of CO\(_2\) fixed. Reason (R): C\(_4\) photosynthetic system is evolved for maximizing the availability of CO\(_2\) while minimizing water loss.
