The purpose of this lettuce lab was to test if photosynthesis performed faster when the plant is receiving its energy from a, ultra violet light. Our hypothesis was that the lettuce would perform photosynthesis faster under an ultra violet light because the wave lengths are closer together than other lights. We are testing if shorter wave lengths produce more energy. The procedure was to use a hole puncher to cut out little circles of spinach leaves and put ten of them in each syringe. The syringes were then filled with a solution of H20 and CO2: two of the three things a plant needs to do photosynthesis. We then suctioned all of the gasses out of the leave circles by creating a vacuum inside of the syringe. This made it so that the leaves were more dense than the solution and the leaves sank to the bottom of the syringe. Then the controlled group was placed under a white light, and the experimental group was places under an ultra violet light. This is the data:
In conclusion, our data rejects our hypothesis.
