Transcript text: The $\square$ is the command center for the cell and contains the cell's DNA.
Solution
The answer is: the nucleus.
Explanation:
The nucleus is the organelle in a cell that serves as the command center. It contains the cell's DNA, which holds the genetic information necessary for the regulation of cellular activities and reproduction.
Other organelles, such as the mitochondria or ribosomes, do not contain the cell's DNA and do not serve as the command center.
