Question

Explain the role of pigments in photosynthesis.

Answer 1

Here is your answer dear⤵⤵⤵⤵

☺☺☺☺




✔Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs --organisms which make their own food usingphotosynthesis. In plants, algae, and cyanobacteria, pigmentsare the means by which the energy of sunlight is captured for photosynthesis.

Answer 2

Answer:

The Pigments involved in the process of photosynthesis are known as Photosynthesis Pigments.

Pigments like Chlorophyll, Carotenoids, (Carotenes and Xanthophylls) anthocyanin, Phycobilins (Phycocyanin and Phycoerythrin) may be found in a plant cell.

Explanation Here !!

Chlorophyll !!

Green pigments in Chloroplast are of mainly seven types. i.e., Chlorophyll a, b, c, d, e, bacterioviridin and bacteriochlorophyll.

The Green Colour of the plant is due to presence of chlorophyll in them.

Chlorophyll traps solar energy and converts it into chemical energy during photosynthesis.

Carotenoids !!

Carotenoids are lipids and can be classified into two groups :-

• 1.) Carotenoids.
• 2.) Xanthophylls.

Extra Information !!

★Orange red in Colour Carotenes are isolated from Carrot.

★ Xanthophylls are of Yellow Colour.

★Carotenoids absorb Light energy and transfer it to Chlorophyll a and thus act as accessory pigments.
