Which of the following statements about Hammerling’s experiment on Acetabularia is/are correct?
(A) It demonstrates that Acetabularia is a unicellular organism. (B) It demonstrates the role of cytoplasm in heredity. (C) It demonstrates the role of nucleus in heredity. (D) It demonstrates the role of cytoplasm in determining rhizoid shape.
Choose the correct answer from the options given below:

Correct option is D

· Hammerling’s experiment on Acetabularia demonstrated that the nucleus is responsible for heredity and determines the genetic characteristics of the organism.
· The experiment involved removing or swapping nuclei between two species of Acetabularia, leading to the conclusion that the nucleus directs cellular development.
· Although Acetabularia is unicellular, the focus of the experiment was on the role of the nucleus, not the unicellular nature.
· Cytoplasmic factors influence morphology but do not control heredity, confirming that hereditary information resides in the nucleus.
