Twilight

Vedclass · Answer

(C) Plants perform photosynthesis during the day (releasing $O_2$) and respiration throughout the $24$-hour cycle (releasing $CO_2$). At twilight (dawn or dusk),the light intensity is such that the rate of photosynthesis exactly equals the rate of respiration. This is known as the compensation point. At this specific intensity,the $O_2$ produced in photosynthesis is entirely consumed by respiration,and the $CO_2$ produced in respiration is entirely consumed by photosynthesis. Consequently,there is no net exchange of gases with the atmosphere.

During $24$ hours,there is a specific time when plants neither release $O_2$ nor $CO_2$. This is the time of:
