Respiration occurs

Respiration in plants occurs continuously, both during the day and night. It is a metabolic process through which plants use oxygen to break down sugars and produce energy for various cellular activities, including growth and maintenance. While photosynthesis occurs mainly during the day when there is light, respiration continues throughout the 24-hour cycle. During the day, photosynthesis and respiration occur simultaneously, but at night, when there is no light for photosynthesis, respiration remains active.
