1.	Identify the incorrect statement.(a) Some photosynthetic pigments absorb light of a particular wavelength at a greater strength, while very less at other wavelength(b) Chlorophyll-a absorbs blue-violet and red colour wavelength at a greater strength, while carotenoids absorb light of blue and green region(c) Action spectrum is a graph which shows the degree of absorption of light by a pigment as a function of wavelength(d) Plant leaves appear green due to high amount of chlorophyll in plant, which reflects green colour
Answer» The statement (c) is incorrect. The graph showing degree of absorption of light by a pigment as a function of wavelength is called absorption spectrum. Action spectrum on the other hand, shows the degree to which different wavelengths affect the rate of photosynthesis.
