Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.
