Solar energy in photosynthesis
Solar energy provides the reducing power within green leaves to convert CO 2 and H 2 O into sugars. The CO 2 is supplied by the atmosphere and enters the leaf by diffusion. Factors affecting the rate of photosynthesis must either change the CO 2 diffusive resistances or the CO 2 concentration gradient along the diffusion pathways. Therefore, these effects can be described
