- Light that the chlorophyll-a pigment uses may be measured by the solar-induced fluorescence (650-850nm). This fluorescence caused by the sun and a plant's gross primary output are correlated linearly. Why does this reasoning shows that solar induced fluorescence can be used to infer net photosynthesis?Solar-induced fluorescence has a linear relationship with a plant's gross primary production. Explain why the relationship is linear?Solar-induced fluorescence can be used to infer net photosynthesis. This is because this solar-induced fluorescence is able to measure the light that is used by the chlorophyll-a pigment (650-850nm). There is a linear relationship between this solar-induced fluorescence and the gross primary production of a plant. How does measuring chlorophyll-a pigment with solar-induced fluorescence help us infer net photosynthesis?
- Why can solar induced fluorescence be used to infer net photosynthesis? Please explain in detail how this is possible.Given the chromatogram of the spinach leaves extract in a normal phase from the experiment you conducted, arrange the components from least polar to most polar. O Carotene, Xanthrophyll, Chlorophyll A, ChlorophyllI B O Chlorophyll B, Chlorophyll A, Carotene, Xanthrophyll O Chlorophyll A, Chlorophyll B, Xanthrophyll, Carotene O Carotene, Xanthrophyll, Chlorophyll B, Chlorophyll AWe perform our measurements for KHP at 281 nm. Would we get the same results for pathlength at 250 nm? What about using chlorophyll at 667 nm? Why might a too high concentration of KHP give erroneous data for measuring pathlength?
- An 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.Explain why the chlorophylls in light-harvesting complexes must absorb light of shorter wavelength than the light that would directly excite the special pair of PSI or PSII.Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?
- What is the relationship between light intensity and the rate of photosynthesis. Make a prediction about this relationship, and identify both independent and dependent variables in the prediction. What will be a suitable hypothesis predict answers for the following: A) what is the rate of germinating peas versus non-germinating peas. B) what is the effect of temperature on germinating peas?To assess photosynthesis, we relied heavily on a spectrophotometer to measure the color intensity of DCPIP in our solution. We set the spectrophotometer at wavelengths in the visible spectrum. What is the approximate wavelength range (in nm) for the visible spectrum? For example, the ultraviolet spectrum wavelength range is approximately 10-400 nmExplain the mechanism of how floating disks correspond to the rate of photosynthesis. What is the purpose of adding baking soda to the leaf disk assay? What would you expect during the leaf disk assay if baking soda was not added at all?
