Scientist use radioactive hydrogen to make water. They grew plants using the radioactive water what happened to the radioactive hydrogen during photosynthesis?

1 answer

During photosynthesis, plants absorb water along with dissolved nutrients and carbon dioxide through their roots. As the water moves through the plant, it's transported to the leaves where photosynthesis occurs. During photosynthesis, the radioactive hydrogen in the water is incorporated into organic molecules, such as sugar and starch, and then used to build new plant tissue.

When the radioactive hydrogen decays, it emits radiation, which can be detected using a radiation detector. By measuring the radiation emitted by the plant tissue, scientists can track the movement of the radioactive hydrogen through the plant and determine how it's used during photosynthesis.
