Bacterial photosynthesis differs from the photosynthesis of others in
The correct option is - B Types of reductant
Blue-Green Algae and autotrophic plants are photosynthetic organisms. They carry out photosynthesis using sunlight, water, and carbon dioxide and produce carbohydrates and oxygen. Photosynthetic bacteria like purple bacteria or green sulfur bacteria carry out anoxygenic photosynthesis. The bacterial photosynthesis differs from the photosynthesis of others in types of reductants. However, they use hydrogen sulfide instead of water as a reductant and elemental sulfur is evolved instead of oxygen.
Thus, the correct answer is 'Types of reductant.'
