(C) Joachim Hammerling performed experiments on the unicellular green alga $Acetabularia$ to demonstrate the role of the nucleus in heredity. He used two species, $Acetabularia$ $crenulata$ and $Acetabularia$ $mediterranea$. In his experiments, he performed grafting by exchanging the $stalk$ (which contains the cytoplasm) and the $rhizoid$ (which contains the nucleus) between the two species. He observed that the characteristics of the cap that regenerated were determined by the species from which the $rhizoid$ (nucleus) was taken, not the $stalk$. Therefore, the parts exchanged in his experiments were the $rhizoids$ and the $stalks$.

In Hammerling's experiments, which part of Acetabularia was exchanged?
