Air as you would be aware is mostly nitrogen secondly oxygen, and in small quantity other gases. Now plant cells during day give off oxygen in the process of photosynthesis. All cells give off carbon dioxide in the process of respiration,release mechanisms may vary. Carbon dioxide is a minor constituent of air. In all it woild not be wrong to say cells give off air.
