C Plants have a blue-green pigment called phytochrome. It is found in almost flowering plants or Angiosperms. Which is utilized to sense light. Acting as a photoreceptor and it controls a number of plant function, including flowering, pigment production, stem growth, and seed germination. It is present in various flowering plants where it helps in the regulation of the time of flowering based on the length of day and night.

Phycobilins absorb light of wavelength
1 $670-700 \mathrm{~nm}$
2 $610-650 \mathrm{~nm}$
3 $500-650 \mathrm{~nm}$
4 $520-520 \mathrm{~nm}$
Explanation:
C Phycobilins are photosynthetic pigments. It is water soluble, blue and red in colour without tail and $\mathrm{Mg}$ found in the phycobilisomes, they are also called accessory pigment. Phycobilins are only present in blue green algae \& Red algae. So it absorb light of wavelength between $500-650 \mathrm{~nm}$.

The chemical structure of chlorophyll a varies from chlorophyll $b$ due to difference between
1 $\mathrm{CH}_{3}$ and $\mathrm{C}_{2} \mathrm{H}_{5}$
2 $\mathrm{CH}_{3}$ and $\mathrm{HCH}=\mathrm{CH}_{2}$
3 $\mathrm{CH}_{3}$ and $\mathrm{CHO}$
4 $\mathrm{CHO}$ and $\mathrm{CH}=\mathrm{CH}_{2}$
Explanation:
C Chlorophyll a and b are two primary types of chlorophyll molecules found in plants. Chlorophyll a has a Methyl group $\left(\mathrm{CH}_{3}\right)$ at the third position of the porphyrin ring, while chlorophyll b has an Aldehyde group $(-\mathrm{CHO})$ at the same position. These altering in structure to contribute in the absorbing the different wavelength of light for broader range of energy for photosynthesis.

Which fractions of the visible spectrum of solar radiations are primarily absorbed by carotenoids of the higher plants?
1 Blue and green
2 Green and red
3 Red and violet
4 Violet and blue
Explanation:
D The chloroplasts include a group of yelloworange pigments known as carotenoids, which mostly absorb blue-green and violet light. As a result, the rate of photosynthesis varies with light wavelength. Carotenoids like- $\beta$-corotens, lycopene, and cryptoxanthin etc.
