Pigments Involved in Photosynthesis

Ans. Pigments are chemical compounds located in the leaves of plants. They play a significant role in photosynthesis by absorbing and reflecting the light waves with specific wavelengths. 

These different wavelengths differentiate the colour of the leaf from each other, due to which different plants have different leaf colours. Pigments like chlorophyll contribute towards the green colour of the leaf and absorb red and blue light most strongly.

Ans. Pigments like chlorophyll contribute towards the green colour of the leaf and absorb red and blue light most strongly. Pigments other than chlorophyll like carotenoids make the leaf’s colour red, orange, or yellow. Along with that, Phycobilins contribute blue-green and reddish colour to algae, and xanthophyll helps make the leaf pale-yellow green. Anthocyanins pigment is responsible for giving a reddish output on the leaf.

Ans. Chlorophyll plays an essential role in photosynthesis because it comes in handy in both chemical reactions and the light reaction of the plant.

Ans. Accessory pigments are compounds capable of absorbing light and are primarily located in photosynthetic organisms. It comprises mainly chlorophyll A, which helps facilitate the absorption scale for different colours and masks the ability of accessory pigments. 

While chlorophyll B and C contribute by reflecting the varying shades of green light, making the leaf look different from others.

Ans. When photosynthetic pigments like chlorophyll B and carotenoids react with protein, the resultant product is a tightly packed antenna-like structure capable of capturing incoming photons. Antenna pigments absorb radiant energy to pump photons into reaction centres as a part of the photosynthetic process. It can be used for manufacturing ATP molecules by exciting an electron with the help of a photon and passing it to the nearby acceptor molecule.
