Assertion (A): plants do not show rise is photosynthesis at higher temperature.
Reason (R): Enzymes of plants are high temperature sensitive as compared to low temperature sensitive enzymes of plants.
Reason (R): Enzymes of plants are high temperature sensitive as compared to low temperature sensitive enzymes of plants.
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 C3 plants are more sensitive to high temperatures due to their enzymes being less stable at higher temperatures compared to C4 plants.
