Question
In the figure given below, the black line (upper) indicates action spectrum for photosynthesis and the lighter line (lower) indicates the absorption spectrum of chlorophyll a. Answer the following:
- What does the action spectrum indicate? How can we plot an action spectrum?
- How can we derive an absorption spectrum for any substance?
Solution
- The action spectrum indicates the rate of photosynthesis. The measurement is oxygen release the oxygen releases on the y-axis and the wavelength on the x-axis can be compared to the action spectrum.
- The absorption of various wavelengths for a particular pigment can be done by processing, such as chlorophyll-a, chlorophyll b, or any other pigment.
