They do. Ever heard of night-blooming flowers? And I have heard you should plant potatoes at night, during certain phases of the moon.
shhhhhhhh cuz they're sleeping
from memory they dont photosynthesise at night and produce carbon dioxide instead of oxygen. this may explain why people feel more tired at night too as the CO2 levels are higher
I think you are wrong I never heard or read that before , Plants making CO2 and SOME people are tired because they were active during the day and their body tells them its time to shut down after dark , Of course true EPers are the exception to this rule we never sleep
lol im nocturnal so that goes in favour of your argument. tis an old memory and possibly incorrect.
Because there are not enough ultraviolet rays for them to collect.
