Vedclass · Answer

(B) During daylight hours,the rate of photosynthesis is significantly higher than the rate of respiration. In active plants,the rate of photosynthesis is typically about $8$ to $10$ times higher than the rate of respiration. Since the stoichiometry of photosynthesis produces $O_2$ in proportion to $CO_2$ fixation,and respiration consumes $O_2$ in proportion to $CO_2$ release,the ratio of oxygen produced to oxygen consumed is approximately $10:1$ under optimal conditions.

During daylight hours,the rate of photosynthesis is higher than that of respiration,and the ratio of oxygen produced to that of consumed is (in $:1$)
