Detailed explanation-2: -Role of air temperature Plant respiration occurs 24 hours per day, but night respiration is more evident since the photosynthesis process ceases. During the night, it is very important that the temperature is cooler than during the day because plants can experience stress.

Detailed explanation-3: -Just as we need to breathe to stay alive, plants must also exchange gases with the atmosphere to function. They need two key gases: oxygen is used in aerobic respiration, where food molecules are broken down to release energy for growth. This process releases carbon dioxide as a waste product.
