Which represents the products of the light-dependent reactions of photosynthesis? For what process are these products needed?

In tomato plants, purple stems (P) are dominant to green (p), and red fruit (R)  is dominant to yellow fruit (r). If a heterozygous purple-stemmed, red-fruited plant were self-fertilized, what proportion of the offspring would have green stems and yellow fruit?
