Select one or more:
a. It is easier to control light intensity than it is to regulate temperature, therefore the investigator chose to measure only light intensity
b. Light intensity affects the rate of photosynthesis more than temperature, therefore the investigator chose to measure only light intensity

d. If different light intensities and different temperatures had been studied at the same time, it would not be possible to know which of these factors affected the rate of photosynthesis.

- Suppose an experiment is performed in which plant I is supplied with normal carbon dioxide but with water that contains radioactive oxygen atoms. Plant II is supplied with normal water but with carbon dioxide that contains radioactive oxygen atoms. Each plant is allowed to perform photosynthesis, and the oxygen gas and sugars produced are tested for radioactivity. Which plant would you expect to produce radioactive sugars, and which plant would you expect to produce radioactive oxygen gas? Explain why.arrow_forwardAs energy passes from blue-absorbing chlorophylls down to red-absorbing chlorophylls, surprisingly, no energy passes from lower energy-absorbing pigments back to higher ones (in other words, the process is irreversible). Why might that be?arrow_forwardThree plants grow side by side in a pond. Glucose and starch are measured for each and shown in relative units below, along with the pH of the vacuole at dawn and at noon. Plant Glucose Starch Vacuolar pH, dawn Vacuolar pH, noon A 100 50 1 4 B 100 10 4 4 C 1,000 2 4 4 Part A:Explain what kind of photosynthesis is being done by each plant with some details about how each works. Justify your answer. Part B:Decipher which plant is biochemically defective after the light-independent reactions and explain how you deciphered this.arrow_forward
- If a plant is removed from its natural environment and exposed to 100 percent CO2 composed of the radioisotope 14C, which of the following will not occur? Select one: a. The rate of photorespiration will remain unchanged. b. The sugars synthesized by the plant will be radioactive. c. The oxygen released will also be radioactive. d. All the carbon molecules in the RuBP molecules will eventually become 14C. e. Rubisco will eventually contain 14C.arrow_forwardIn a photosynthetic investigation, a student measured the following pH of the stroma and the inner thylakoid compartments of spinach leaf cells at the conclusion of the experiment. Source of Fluid pH (mean) Standard Error of Mean (SEM) Stroma 8.2 0.75 Inner compartment of thylakoid 5.6 0.35 Describe the stages of photosynthesis. Explain the need for a constant supply of inorganic carbon dioxide.arrow_forwardIn the photosynthesis lab, a group of students found that in the blue light condition, there was a change in absorbance (ΔA620) of 0.324 in extracted spinach chloroplasts. The students later went on a hike and located a plant they had never seen before and were interested in how the photosynthesis rates would compare to their experiment with spinach chloroplasts. They extracted chloroplasts of the unknown green-leaved plant and exposed them to the same experimental conditions as before. The students calculated the ΔA620 to be 0.100. Which plant (spinach or unknown) has the highest rate of photosynthesis? Explain your answer using evidence, being sure to demonstrate your understanding of the dependent variable.arrow_forward

If you measure leaf photosynthesis at different time, how would temperature influence your leaf photosynthesis measurement? What’s the best time for leaf photosynthesis measurement in a day?arrow_forwardAn experiment was done to determine how color of light and distance affects photosynthetic activity of the pond weed. Pond weed was placed in a test tube containing a solution of sodium hydrogen carbonate, and had its end cut; light was placed 50 cm away and four colors were tested (clear, red, blue, and green). After placing the light, the pondweed was given a certain amount of time to adjust before counting the bubbles, bubbles were counted for 1, 3, and 5 minutes. Only the bubbles that came out of the cut end was counted to represent the rate of photosynthesis. Below is the tabulated results. What are the possible factors or errors that could have affected clear/white light to have lower photosynthetic activity? In theory this should have the highest rate.arrow_forward
