Which organelle stores genetic material and controls the cell's activities?

• A. Genotype
• B. Chloroplast
• C. Nucleus
• D. Phenotype

Answer: (C)

The nucleus stores genetic material and acts as the cell’s control center. It houses DNA, which carries the instructions for making proteins that drive nearly all cellular processes. By regulating which genes are turned on or off, the nucleus directs how the cell grows, responds to its environment, and carries out its functions. Other terms describe traits or other structures: genotype is the genetic makeup, phenotype is the observable traits, and chloroplast is an organelle mainly involved in photosynthesis and is not the master regulator of the cell’s activities.
