Assertion (A): plants can tolerate high temperature conditions.
Reason (R): Enzyme pepcase and PPDK work only on high temperature.
Reason (R): Enzyme pepcase and PPDK work only on high temperature.
View answer and explanation
Correct option: A
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Option A (Both (A) & (R) are true and the (R) is the correct explanation of the (A)) is correct because C4 plants can tolerate high temperatures due to the enzymes PEPcase and PPDK functioning optimally at higher temperatures.
