Question

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.

• A. Both A and R are correct. R is the correct explanation for A.
• B. Both A and R are correct, but R is not the correct explanation for A.
• C. A is correct but R is incorrect.
• D. A is incorrect but R is correct.

Hint:

C\(_4\) plants have an efficient mechanism that allows them to minimize water loss while still fixing carbon efficiently.

Answer 1

The Correct Option is A

C\(_4\) plants lose less water compared to C\(_3\) plants because their photosynthetic system is more efficient in capturing CO\(_2\) while minimizing water loss. This makes the assertion (A) true, and the reason (R) correctly explains the assertion.
