What organelle is known for controlling cell activities?

• A. Nucleus
• B. Mitochondrion
• C. Ribosome
• D. Cytoplasm

Answer: (A)

The nucleus is known as the control center of the cell, as it houses the cell's genetic material in the form of DNA. This organelle is responsible for regulating various cellular activities, including growth, metabolism, and reproduction, by controlling gene expression. The information stored in DNA is translated into proteins through processes like transcription and translation, which ultimately dictate how the cell functions. In contrast, the mitochondrion is primarily involved in energy production through cellular respiration, while ribosomes are essential for protein synthesis. The cytoplasm serves as the medium where cellular processes occur, but it does not have a direct role in controlling cell activities. Thus, the nucleus stands out as the organelle that directly governs and coordinates the overall functions and activities of the cell.
