The upcoming discussion will update you about the differences between C3 plants and C4 Plants. Difference # C3 Plants (Calvin Cycle): 1. Optimum temperature for photosynthesis is 10-25°C. 2. Atmospheric concentration of oxygen (21%) reduces the rate of photosynthesis which is optimum at 2-4% O2 concentration. 3. Saturation point is reached at 10—70% of full […]
