NEET Biology question
Study the following statements. (i) Red light falling in the range of wavelength 660-760 nm is the most effective for photosynthesis. (ii) Green light falling in the range of wavelength 500-580 nm is the least effective for photosynthesis. (iii) Chlorophyll-a, chlorophyll-b, carotenes and xanthophylls are soluble in organic solvents. (iv) Phycobilins (phycocyanin, allophycocyanin and phycoerythrin) are soluble in water. Which of the above statements is/are incorrect?
Answer: (D)
Solution
All four statements are accurate descriptions of light-wavelength effectiveness and pigment solubility, so none of them is incorrect.
