Do trees give off oxygen after you cut them down?

    No, since  photosynthesis takes place primarily in parts of the leaves (upper/lower epidermis, mesophyll, veins, and stomates). Without leaves there is no chemical process of photosynthesis.

    Maybe for a very short time, but like iphigenia said, once the leaves are dead photosynthesis desists.

    Once trees are dead, they do not produce oxygen. In fact, they do the exact opposite.

    Instead of using CO2 and producing oxygen and carbon, they begin to produce CO2 (and other gases) once they start to decompose. Technically, it’s the bacteria that are breaking down organic matter which produce the CO2, and not the organic matter itself.
