The activities of a cell are directed by which structure?

The activities of a cell are directed by which structure?

• A. The mitochondria
• B. The nucleus
• C. The Golgi apparatus
• D. The endoplasmic reticulum

Answer: (D)

The nucleus acts as the control center of the cell. It contains the cell’s DNA and regulates gene expression, which determines which proteins are made, when they’re made, and in what amounts. Those proteins then drive the cell’s activities and functions. While the endoplasmic reticulum handles the synthesis and transport of proteins and lipids, the actual direction of cellular activities comes from the nucleus through control of what gets produced.
