Question

4 Is it possible for a plant to be photosynthesising and respiring at the same time
​

Answer 1

Yes, plants can do photosynthesis and cellular respiration at the same time. ... In order to use this food for energy, the plant must perform cellular respiration. Just like in animals, glucose is broken down during cellular respiration in plants to produce energy in the form of ATP

Answer 2

Photosynthesis occurs only during the day in plants and algae , cellular respiration occurs both Night and Day . The two processes take place in different cellular organelles (The cholroplast and mitochondria , respectively and occur simultaneously)
