Select the incorrect statement from the following?
1 Most of the photosynthesis takes place in the blue and red regions of the spectrum
2 Some photosynthesis does takes place at the other wavelengths of the visible spectrum
3 Chlorophyll is the accessory pigment responsible for trapping light
4 All are correct
Explanation:

Which of the following options is/are correct for accessory photosynthetic pigments?
1 They include chlorophyll-a, xanthophylls and carotenoids
2 They absorb light and transfer to chlorophyll-a
3 They enable absorption of wider range of wavelength of incoming light for photosynthesis
4 2 and 3
Explanation:
Accessory pigments include chlorophyll b, xanthophylls and carotenoids.

Statement A : Most of the photosynthesis takes place in the blue and red regions of the spectrum Statement B : Accessory pigments protect chlorophyll a from photoreduction
1 Statement-A is correct but Statement-B is incorrect
2 Statement-A is incorrect but Statement-B is correct
3 Both the statements are correct
4 Both the statements are incorrect
Explanation:
Most of the photosynthesis takes place in the blue and red regions of the spectrum; some photosynthesis does take place at the other wavelengths of the visible spectrum. Accessory pigments not only enable a wider range of wavelength of incoming light to be utilised for photosyntesis but also protect chlorophyll a from photo-oxidation.

Which light range is least effective in photosynthesis?
1 Blue
2 Green
3 Red
4 Violet
Explanation:
Because chlorophyll, the pigment involved in photosynthesis is green (for the most part, there are other forms that are not green) and because it is green it reflects green wavelengths of light and does not absorb them.Plants need to absorb light to perform photosynthesis.
