Assertion: Accessory pigments enable a wider range of wavelength of incoming light to be utilised for photosynthesis.
Reason: Accessory pigments also protect chlorophyll a from photo-oxidation.

Assertion :- Presence of accessory pigments enhances rate of photosynthesis. Reason :- They enable a wider range of wavelength of incoming light to be utilised for photosynthesis.

Carotenoids are I. yellow to orange pigments, which absorb light strongly in the blue - voiltet range. II. Called shield pigments because they protect chlorophyll from photo -oxidation. III. Magnesium porphyrin compounds. IV. Red and blue pigments

A : Carotenoids protect plant from excessive heat and prevent photoxidation of chlorophyll. R : Carotenodis enable a wider range of wavelength of incoming light to be utilised for photosynthesis.

A : Carotenoids protect plant from excessive heat and prevent photoxidation of chlorophyll. R : Carotenodis enable a wider range of wavelength of incoming light to be utilised for photosynthesis.

Which of the following statement is / are incorrect ? (i) Green light falling in the range of wavelength 500 -580 nm is least effective for photosynthesis. (ii) In non - cyclic photophosphorylation, the electron expelled from the reaction centre is not cycled back , though its loos is compensated by electrons from the photolysis of water . (iii) Chl a , Chl b , carotenoids , and xanthophylls are insoluble in organic solvents. (iv) 400-700 nm light is used in photosynthesis also known as PAR. (v) Red light is the most effective for photosynthesis.

Assertion : Carotences and xanthophylls are soluble in ether. Reson : There are accessory pigments of photosynthesis.

How is light energy transferred by the accessory pigments during photosynthesis?

Identify the correct statements from the below about ''Carotenoids''. (I) Carotenoids are yellow to orange pigments (II) Mostly tetraterpens (III) These pigments protect chlorophyll from photooxidative damage. (IV) Also they are called tetraterpenoids

Chlorophyll 'a' is the primary pigment for light reaction. What are accessory pigments? What is their role in photosynthesis?
