Do trees and plants need oxygen to survive?

Oxygen is a waste product. The trees take in CO2 and release oxygen as a waste product. However, I’m seeing sites that suggest that oxygen is needed as part of the process. I don’t understand. Why would a tree need something it gets rid of as a waste, any more than we would need something back that we give off as a waste.
