The photosynthetic rate in a test tube can be determined by collecting and measuring the amount of oxygen?
that gases out of water. If bicarbonate, the source of carbon dioxide for aquatic plants, is added to the water, the rate of oxygen evolution increases. If carbon dioxide is fixed by the calvin cycle, but oxygen is evolved in the light reactions, how can an increase in co2 supply increase the rate of oxygen evolution?
wow.....confusing
