depends on 42

subjecting an experimental group of plants to an atmosphere with a higher oxygen concentration

subjecting an experimental group of plants to an atmosphere with a higher carbon dioxide concentration

subjecting an experimental group of plants to a special soil that has been enriched with a new fertilizer

subjecting an experimental group of plants to air that gaseous nitrogen has been added to

individual oxygen atoms are formed during photosynthesis.-c.
