Question based on Introduction to Photosynthesis in higher Plants| Historical account part 1 |Historical account part 2 |Photosynthetic pigments

Assertion: Chlorophyll a is the chief pigment associated with photosynthesis. Reason: In the blue and red regions of spectrum, there is maximum absorption by chlorophyll- a, also shows higher rate of photosynthesis

Which of the following statements with regard to photosynthesis is/are correct? I. In C3 plants, the primary CO_2 acceptor is RuBP. II. In the photosynthetic process, PS-II absorbs energy at or just below 680 nm. III. The chlorophyll-a that is present in the photosystem-I has absorption maxima at 680nm.

A pigment appears yellow-orange in the chromatogram and found in leaves of higher plants, helps (a) In absorption of light of different wavelength (b) To prevent oxidative destruction of chlorophyll pigment by light. (c) By absorbing wavelengths beyond visible spectrum which increases the efficiency of photosynthesis.
