The control center of a cell is called the nucleus.
The nucleus plays a crucial role in controlling the activities of the cell. It contains the cell's genetic material, which is organized into structures called chromosomes. These chromosomes carry the instructions for the cell's functions and determine its characteristics.
Key Points:
- The nucleus is often referred to as the control center of the cell.
- It contains the cell's genetic material, including DNA and RNA.
- The nucleus controls the cell's activities by regulating gene expression.
- It is surrounded by a nuclear membrane, which separates it from the cytoplasm.
- The nucleus also contains a nucleolus, which is responsible for producing ribosomes.
- The nucleus is involved in processes such as cell division and protein synthesis.
Therefore, the correct answer is A: nucleus.
