Many people study photosynthesis in plant leaves, but since the pods and immature seeds (edamame) of soybean plants are also green, they are receiving chlorophyll and should be studied as well. Researchers with the RIPE Project discovered that chlorophyll in soybean pods plays a vital role in the plant’s photosynthetic process and significantly contributes to soybean yield.
