1.	Which of the following is most sensitive to higher wavelengths of sunlight?(a) Photolysis(b) Chlorophyll(c) PS I(d) PS III had been asked this question in a national level competition.My question is from Higher Plants Photosynthesis topic in section Photosynthesis in Higher Plants of Biology – Class 11
Answer» RIGHT answer is (c) PS I Explanation: Photosystem I is most sensitive to higher wavelengths of SUNLIGHT. It is because its absorption maxima are 700nm which GIVES it more strength to CAPTURE wavelengths of light. PS II is not as much sensitive as PS I since it has absorption peak only at 680nm.
