Solution

The correct option is A Acetabularia
Nucleus is a double membrane covered protoplasmic body that contains hereditary information. With the help of grafting experiments on Acetabularia, Hammerling (1953) proved that nucleus is a store-house of hereditary information and hence, controls growth because growth depends on proteins synthesized and protein synthesis depends on the hereditary information.
