What supervises cell activity?

1. Ribosomes

2. Nucleus

3. Cytoplasm

4. Cell membrane

The correct answer is: Nucleus

The nucleus is often referred to as the control center of the cell because it houses the cell's genetic material (DNA) and is responsible for regulating gene expression. By controlling which proteins are produced and in what quantities, the nucleus plays a crucial role in directing cell activities, including growth, metabolism, and reproduction. It also coordinates cellular responses to environmental signals. For instance, when a cell needs to respond to a particular stimulus, the nucleus can activate specific genes that lead to the production of proteins required for that response. This capability makes the nucleus essential for the proper functioning and regulation of cellular processes, setting it apart as the primary supervisor of cell activity.
