Solution(By Examveda Team)

The pathway of carbon in photosynthesis was discovered by Calvin.
Calvin shone a light on the lollipop and used a radioactive form of carbon called carbon-14 to trace the path that carbon took through the algae's chloroplast, the part of the cell where photosynthesis occurs. By this method, he discovered the steps plants use to make sugar out of carbon dioxide.
