Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R). 

Assertion (A): The temperature optimum for photosynthesis of different plants also depends on the habitat that they are adapted to.
Reason (R): Temperate plants have a higher temperature optimum than the plants adapted to tropical climates.
In light of the above statements, choose the correct answer from the options given below. 

Assertion (A) is true because the temperature optimum for photosynthesis of different plants indeed depends on the habitat they are adapted to. Plants have evolved to thrive in specific environmental conditions, including temperature ranges, which affect their photosynthetic efficiency.

Reason (R) is false because tropical plants often have a higher temperature optimum for photosynthesis compared to temperate plants. This adaptation allows tropical plants to thrive in the consistently warm climates characteristic of tropical regions. In contrast, temperate plants are adapted to a wider range of temperatures, including cooler conditions typical of temperate climates.

Therefore, A is true but R is false.
