Vedclass · Answer

(B) Joachim Hammerling conducted experiments on the unicellular green alga $Acetabularia$ to determine the role of the nucleus in heredity. He used two species,$Acetabularia$ $crenulata$ and $Acetabularia$ $mediterranea$. By performing grafting experiments,he observed that the cap morphology (the shape of the umbrella-like structure) was determined by the nucleus present in the rhizoid. When the nucleus of one species was transplanted into the stalk of another,the regenerated cap always resembled the species from which the nucleus was derived. This proved that the nucleus contains the genetic information responsible for controlling cellular traits and heredity.

Hammerling's experiment on $Acetabularia$ proved the role of:
