Yellow light absorbing pigment
B
Pigment of cryptogams
C
Red light absorping pigment
D
Blue light absorbing pigment
Answer
Blue light absorbing pigment
Explanation
Solution
Answer (d) Blue light absorbing pigment
Cryptochromes are blue light absorbing pigment and are photoreceptors. Cryptochromes have flavin adenine dinucleotide that gives them the ability to absorb blue light. When they absorb light, FAD undergoes photochemical reaction that result in the conformational changes within the protein. These make them functional for the biological processes.
