I'm really lost on AP Bio and if anyone can explain how you would answer each of these it would be very appreciated !!! <3

Read each question carefully. Write your response in the space provided for each part of each question. Answers must be written out in paragraph form. Outlines, bulleted lists, or diagrams alone are not acceptable and will not be scored.


Researchers tested the effect of light on the rate of photosynthesis by a species of shrub growing under conditions that differ widely in the amount of available light but where the availability of water and soil nutrients is fairly constant. Under constant temperature, relative humidity, and leaf surface area, the researchers used increasing illumination (measured as photosynthetic photon flux density, the number of photons of wavelengths between
and
nanometers per unit surface area and unit time) and determined the net photosynthesis (measured by the amount of carbon dioxide fixed per unit surface area and unit time at each illumination) of the shrubs growing in full sun, partial sun, or in shade (attached screenshot).


a) Describe how plants absorb photons of light energy.
b) Using the template, construct an appropriately labeled graph to represent the data in Table 1.
c) Based on the data, identify the shrubs and data point where the greatest flow of electrons through chloroplast electron transport chains most likely occurs.
d) Predict the effect on shrubs growing in one area if they are treated with a compound that blocks electron flow through the electron transport chains of chloroplasts. Provide reasoning to justify your prediction.
