Diagram 7: Rate of Photosynthesis with increasing light intensity 200 150 100 50 -50- -100 100 200 300 400 500 600 700 Light Intensity (arbitrary units) Glossary: 1. Pmax: The maximum pressure of oxygen gas. 2. Arbitrary units: The use of this term mean the graph is not using specific units as labels. Light intensity could be measured in lumens and oxygen production could have been measured in mm of Hg elect the best explanation for the oxgen production leveling off as the light increases in intensity. O More light reduces the activity of the chlorophyll by breaking the pigment down. More light prevents water from getting to the leaf cells to be split. OHigher light intensity has less blue and red wavelengths Photosystem l and Il in the light dependent reactions have a maximum limit on how many light photons they can capture w their chlorophyl pigments. Photons…Look at the figure and answer the following question : The blanks A and B in stage 1 can be filled as : * Captionless Image A : chlorophyll B: air A : chlorophyll B: sunlight A : mitochondria B: air A : mitochondria B: sunlightIn 1770, Joseph Priestley performed a series of experiments to determine the reactants and products of photosynthesis. The diagram below shows the experimental conditions and results of two experiments performed by Priestley, named here as Experiment 1 and Experiment 2. From his experiments, Priestley concluded that plants restore to the air whatever breathing animals and candles remove. Joseph Priestly Photosynthesis Experiments and Results Experiment Results: - candle extinguished (went out) 1 - mouse died Experiment 2 Results: candle continued to burn mouse stayed alive Note: Experiment 1 and Experiment 2 were both performed in the presence of sunlight. The substance produced by the plant in Experiment 2, that keeps the candle burning and the mouse alive is O CO2 O 02 O H2O O C6H1206

- Diagram 8: Temperature and Rate of Photosynthesis 5 10 15 20 25 30 35 40 temperature (°C) The most accurate explanation for lower rates of photosynthesis at high temperatures would be The water splitting enzyme and ATP synthase will change their shapes at higher temperature and not function properly. There is less light at high temperatures to power the light dependent reactions. Less O2 is available to power the Calvin Cycle when temperatures are high. There is a lower availability of CO2 for photosynthesis at higher temperatures. rate of photosynthesisPhotosynthesis can only be powered by sunlight. true or false explain in 3-4 sentencesFor each of the conditions listed below, would the rate of photosynthesis increase, decrease, or stay the same?
