Reflected light refers to those wavelengths of light that will "bounce off" of the chlorophyll and not be absorbed. A scientist runs an experiment in which only light waves measuring between 490 and 600 nm are hitting the plant. Select the answer that would explain what would happen based upon the data in the chart. Chlorophyll a would absorb high amounts of light energy, but chloroplyll b would be absorbing low amounts of energy. Neither chlorophyl a nor b would be absorbing very much, if any, light energy. Chlorophyl b would absorb high amounts of light energy, but chlorophyll a would be absorbing low amounts of energy. Both chlorophyl a and b would be absorbing high amounts of light.
Light Leaf B Leaf A Black cloth КОН Water solution Take a close look at the apparatus, it is set up to investigate factors that affect the rate of photosynthesis. KOH solution is similar to sodium hydroxide. The plant was placed in the light for 24hrs in the state that is seen. Following 24 hours leaf A and B were tested for starch. Explain what results we would expect to see and why?
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 nm
