When you measure changes in atmospheric co2 in the light are you measure net photosynthesis or gross photosynthesis???
Answer
gross photosynthesis
When you measure changes in atmospheric co2 in the light you are measuring theĀ gross photosynthesis
Explanation
This is because the gross photosynthesis is true photosynthesis (carboxylation) while on the other hand, net photosynthesis is true photosynthesis minus photorespiration and dark respiration. Additionally, gross photosynthesis is intended as an integration of apparent photosynthesis which is true photosynthesis minus photorespiration.
