Limiting Factors in Photosynthesis — NEET Biology
📚 Practice ConceptBased on the graph, answer the following questions: (a) At which point/s (A, B or C) in the curve light is a limiting factor? (b) What could be the limiting factor/s in region A? (c) What do C and D represent on the curve?
Which of the following statements about the requirements and associated components of photosynthesis are correct? S1: Chlorophyll 'a' is the chief pigment directly involved in trapping light energy for photosynthesis, while accessory pigments broaden the absorption spectrum. S2: Water serves as the electron donor in oxygenic photosynthesis and is the source of all oxygen released. S3: Carbon dioxide is fixed in the stroma to synthesize sugars, utilizing the energy from ATP and NADPH produced in the light reaction. S4: Mitochondria are indispensable cellular organelles where the light-dependent reactions of photosynthesis primarily occur. S5: Optimal light intensity for photosynthesis is always full sunlight, as higher intensities never lead to chlorophyll degradation.
