Assertion: `C_(4)` pathwat of `CO_(2)` rixation is found in some tropical plants.
Reason : In this pathway `CO_(2)` is fixed by 3C compound.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer

A

Explanation

The plants that perform `C_4` cycle are found in tropical (dry and hot regions) and subtropical regions found in both monocot and dicot plants.
In this pathway, the carbon dioxide of the atmosphere comes in contact with mesophyll cells where it combines with 3C compound (Phosphoenol pyruvic acid) to form a 4c compound (Oxaloacetic acid).
