Are you meaning C02? I dont believe aquatic plants give off oxygen bubbles right off the bat.
Oh, Just a note, the plant with the long green and light green strips is not truly aquatic. Slowly, it will decay over time and bring ammonia in the aquarium. Just get it out and put it in a pot of soil.
They will take in oxygen but not any that will starve the fish of it. At night, the plants take in oxygen and produce carbon dioxide, then the process if reverse in at daytime. Nothing to worry about.
