1 Lab #5: Photosynthesis Lab Report Template Name: JIMMY TSZ YUEN CHAN Use this form to complete this week’s lab report assignment as directed in the BIOL 100L Lab5 Photosynthesis file. Once complete, the file should be saved as a pdf with the file name that follows this format: Your full name JIMMY TSZ YUEN CHAN _BIOL100_Lab5 Part 1: Developing a photosynthesis measurement system Temperatures ( C): Beginning: End: Results and notes: record what factors were changed and any relevant observations Trial 1: 20 C 28 C The experiment did not reach the ideal time but it succeeded without changing any factor. Trial 2: Trial 3: Table 1. Data collected for the development of an effective photosynthesis system for Part 1. Summary Notes: The experiment was successful within the first trial therefore no subsequent trials were performed. That is the leaf buoyancy was noted within the first 10 minutes when the leaf disks were exposed to sodium bicarbonate and the light bulb. The experiment proved that photosynthesis takes place when there is carbon dioxide, light and energy. The leaf disks had to be fresh to ensure there was enough chlorophyll for photosynthesis to take place. The results obtained proved that photosynthesis took place because the leaf disks floated after a while. They floated due to the accumulation of oxygen which pushed them up to the surface of the water. The leaf disks had to be placed at the bottom and all air succeed from them so that the development of photosynthesis would be noted once the leaf disks float on water. The increase in temperature at the end of the experiment was due to the ATP produced as a byproduct of the experiment. Table 2. Summary of your successful photosynthesis system; note specific leaf source, light system, things that you will be carefully monitoring during the actual experimental trials of Part 2, etc. Part 2: Evaluating carbon as a limiting factor in photosynthesis Question A: If carbon dioxide concentration is low, would expect the plant cells to not photosynthesize at all or would you expect the rate of photosynthesis to simply slow down? Explain your reasoning.

2 If the concentration of carbon dioxide is low, I would expect that the rate of photosynthesis would slow down. This is because the concentration is only low not zero. At zero concentration of carbon dioxide, no

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
