Compared Rates of Photosynthesis Using Different Light The rates of photosynthesis were compared in different lighting conditions. Two syringes were filled with a bicarbonate detergent solution. Ten leaf diskettes were placed in each syringe filled with the bicarbonate solution and then placed in different lighting conditions. The color of the lights which the syringes were placed were red and white. After the two syringes were placed underneath the lights then results were recorded after certain periods of time. The light made the leaves go through the process of photosynthesis which resulted in the leaves floating to the top of the syringes. Results were recorded as each leaf diskette either floated to the top or did not float to the top. When the light reactions produced oxygen, liquid was forced out of the air spaces and the leaf disks became buoyant in the solution enough to float, then the faster they were photosynthesizing the faster that they would float to the top. Introduction The rates of photosynthesis under different light conditions. The rates of photosynthesis were measured by the length of time it took leaf diskettes punched from leaves to go through the process of photosynthesis and rise to the top of a bicarbonate-filled syringe. The rates showed how measurable quantities can change over time. As oxygen gas was produced by photosynthesis in the leaf diskettes, the measurement was determined by measuring the amount of oxygen that the leaf diskettes produced in certain periods of time (Buchanan, 2006). Methods and Materials Two leaves had ten pieces punched out of each with a hole punch. A syringe barrel was then used to place the diskettes inside. Five cc’s of bicarbonate detergent were then placed inside each syringe. The syringes were then inverted and each was tapped on to release air bubbles. The plungers were then placed
