Question

The two accessory photosynthetic pigments present in the leaves are
A. Carotene and chlorophyll
B. Xanthophyll and chlorophyll
C. Anthocyanin and carotene
D. Xanthophyll and carotene

Answer 1

Hint: Photosynthetic pigments are the ones that help in the process of photosynthesis, they are found inside the chloroplasts and they pass on the absorbed light to the light-harvesting complexes present in the inner and outer membrane of the thylakoid.

Complete answer: Photosynthesis is the process of production of sugars and oxygen along with energy in the presence of light and carbon dioxide.
1. Various light-harvesting complexes are involved in this process which absorbs the sunlight and makes it available to the plant for photosynthesis.
2. Photosynthetic pigments present in the chloroplasts, absorb the light and transfers it to the photosystems. These pigments may be primary or accessory.
3. The primary Photosynthetic pigments are the chlorophyll a and chlorophyll b which absorb the green light while accessory pigments are the ones which a sort different wavelengths of light and pass it to the primary pigments.
4. Accessory pigments are the xanthophylls and carotenoids.

Additional information: Photosynthesis is very important to live organisms because it is the major of oxygen in the atmosphere.
Green plants and trees use photosynthesis to produce food from sunlight, carbon dioxide, and water in the atmosphere: It is their primary and utmost source of energy.

Hence, the correct option is (D), xanthophyll, and carotene.

Note: Primary pigments pass on the electrons to the light-harvesting complexes. The accessory pigments also past the captured light to the primary pigments.
