Respiration in plants occurs 24 hours, however, the respiration in the night is more evident because the process of photosynthesis ceases down. It is essential during the night that the temperature is lower than that of the day since plants experience a lesser stress. As the temperature in the night increases, the respiration rate and the temperature in plants tends to increase. This might lead to poor plant growth and flower damage. This is the reason we often see dead flowers and leaves in the morning. Hence, the temperature of the air plays an essential role when it comes to the respiration in plants.
