Niels Bohr proposed the atomic Bohr model in 1915. It was created by modifying Rutherford's atomic model. The nucleus model was developed by Rutherford, who suggested that a positively charged nucleus is surrounded by negatively charged electrons.

BOHR’S ATOMIC MODEL

The nucleus regulates and maintains the growth and metabolism of the cell. The nucleus is the most important component of the cell.
