Expert Solution & Answer

Explanation of Solution

Blackman measured photosynthesis rates under differing intensities of light, carbon dioxide, and temperatures. Blackman found that increasing light intensity above 2000 foot-candles does not lead to any further increase in the rate of photosynthesis.

The light energy is used to generate adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) that can then be used to reduce carbon dioxide. The chlorophyll molecules absorb the photons of light energy. Thus, increasing light intensity increase photosynthesis, but it will saturate when all chlorophyll molecules are in use.

When discussing why the rate of photosynthesis did not increase at higher light intensities, the investigator mentioned the possibility that high light intensities could damage chlorophyll, which would result in a decrease in oxygen production. Which of the following accurately explains the role of chlorophyll in oxygen production during photosynthesis and why damage to chlorophyll would results in lower oxygen production? Select one or more: a. Chlorophyll participates in carbon fixation during the Calvin Cycle. During this process, oxygen molecules are formed. b. Chlorophyll captures energy from sunlight and releases high energy electrons that enter the electron transport chain in the Calvin Cycle. During this process, oxygen molecules are formed. c. Chlorophyll participates in carbon fixation during the light reactions. During this process, oxygen molecules are formed. d. Chlorophyll captures energy from sunlight and releases high energy electrons that enter the electron…

In an experiment conduct to know the effect of light intensity on the rate of photosynthesis in spinach leaves, with the use of 5 ml of a 0.2% sodium bicarbonate (NaHCO3) and a solution of dilute drop of liquid soap. in relation this experiment, state an hypothesis that predicts the relationship between light intensity and the rate of photosynthesis. Identify independent and dependent variables. What is your control group, and why is this an appropriate control?

In 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
