Question

Select incorrect statement

• A. each photosystem has all the pigments except one molecule of chlrophyll a
• B. Action spectra is greater in blue and red light
• C. Chlorophyll a and b are primary pigments associated with photosynthesis
• D. PS II is involved in evolution of $O_2$

Answer 1

The correct option is C Chlorophyll a and b are primary pigments associated with photosynthesis

Light reaction of photosynthesis occur by the involvement of two photosystems, namely photosystem I and II. Every photosystem has a reaction centre and light harvesting complex. In the reaction centre chlorophyll a is present, whereas light harvesting complex contains all photosynthetic pigments. Photosystem II is involved in evolution of oxygen.

So, the correct option is, 'Chlorophyll a and b are primary pigment associated with photosynthesis'.
