The part of a cell that controls the cell’s activities is the nucleus.

Quick Scoop: Why the nucleus?

  • The nucleus stores DNA, the genetic material that carries instructions for all cell functions.
  • These instructions tell the cell when to grow, divide, make proteins, and respond to the environment.
  • Because it directs and regulates these processes, the nucleus is often called the cell’s “control center” or “brain.”

In simple terms: the nucleus is the command center that runs almost everything the cell does.

TL;DR: The nucleus controls most of the cell’s activities.
