What does your science teacher say?

Couldn't you find any websites on photosynthesis when you did your Google
search?

I understand that when sunlight is around trees and plants will give off
oxygen and soak up carbon dioxide (photosynthesis) - but at night is it
true
that they will give off carbon dioxide? If so, how much of each will be
released during the night and day.

Thanks for any answers.

P.S. At night do they take in oxygen?
