When James Cameron was working on his character, Rose Dewitt Bukater Calvert for the film Titanic, he had already envisioned a feisty character with a dominating mother. Bill Paxton's wife was reading Beatrice's Wood's autobiography.
photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
Processes in photosynthesis are divided on basis of requirement of sunlight while respiration processes are divided on basis of requirement of oxygen. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration.
