Are bubbles signs of oxygen?

I'm creating an enclosed rainwater ecosphere for the first time, I've created 3 with extra bottles I had. I put plants in all 3 and a avocado seed in another (I tried growing it but it never sprouted so I thought I'd experiment by putting it in my ecosphere). There are little bubbles all over the plant and seed in this one, is this a sign of the plants living? Or is there another reason? Either way I'm interested to understand.

    Whilst I don’t fully understand your setup, plants & trees produce oxygen so if its underwater and are able survive then yes it would come to the surface in bubbles.
