Why does chlorophyll appear green in reflected light and red in transmitted light? Explain the significance of these phenomenon in terms of photosynthesis.
Significance of absorption spectrum : (a) It is the property of the chlorophyll to absorb certain rays of light. The light is splitted up into seven colours and these colours form a series called spectrum.
(b)The absorption spectrum of chlorophyll is maximum for the red light. 700 nm and it appears red in the transmitted light.
©This absorption spectrum for red light facilitates the process of photosynthesis to the maximum.
The chlorophyll appears green in reflected light because green light of sunlight is not absorbed by the chlorophyll but is reflected back.
