I personally disagree..there is a difference.
Given the facts of plant photosynthesis.
During the collection of energy which would be the daylight period is collected in the plants leaves. This energy is then converted and used by the plant during the dark period. Most of which occurs within the first 2-4 hours of the dark period.
"Photosynthesis Summary
In summary, photosynthesis is a process in which light energy is converted to chemical energy and used to produce organic compounds. In plants, photosynthesis occurs within the chloroplasts. Photosynthesis consists of two stages, the light reactions and the dark reactions."
My 2 cents
