WebDr. Joachim Hämmerling ForMemRS (9 March 1901 - 5 August 1980) was a pioneering Danish-German biologist funded by Nazi Germany who determined that the nucleus of a cell controls the development of organisms. His experimentation with the green algae Acetabularia provided a model subject for modern cell biological research, and proved the … Acetabularia are among the largest single-celled organisms, having also a remarkably large nucleus. During sexual reproduction , the nucleus undergoes multiple rounds of mitosis , forming many daughter nuclei all within one nuclear membrane.
