Verified step by step guidance
1
Identify the organelle that contains the majority of the cell's genetic material (DNA).
Recall that the organelle housing DNA is responsible for regulating gene expression and controlling cellular activities.
Understand that the nucleus is the membrane-bound organelle that stores DNA and manages gene expression through transcription.
Compare the functions of the other organelles: Golgi apparatus modifies and packages proteins, ribosomes synthesize proteins, and mitochondria generate energy.
Conclude that the nucleus is considered the cell's control center because it contains most of the genetic material and regulates gene expression.
