Answer:
True.
Explanation:
The temperature of sorghum could be lower than 40°C when the surrounding temperature is 40°C because the sorghum plant absorb the sunlight and used it in the process of photosynthesis and the transpiration process regulate the body temperature of sorghum plant. Transpiration is the process in which water evaporated through a plant and its aerial parts, such as leaves, stems and flowers. This process removes extra heat with water through stomata so we can say that the temperature of sorghum is lower than 40°C.
