Answer: Nucleus
Step-by-step explanation:
The nucleus is like a conductor of an orchestra because both control and coordinate activities.
In a cell, the nucleus is considered to be the most important organelle due to it being the control center. Like a conductor does in an orchestra, the nucleus controls and coordinates activities to ensure the cell's survival.
It does this primarily by controlling protein synthesis due to it being the structure that houses DNA which in turn contains the instructions for synthesizing protein.
