Function of the cell is controlled by

Options

A. Protoplasm
B. Cytoplasm
C. Nucleolus
D. Nucleus

Answer

To answer the question "Function of the cell is controlled by," we can follow these steps:

1. **Identify the Options**: The options given are protoplasm, cytoplasm, nucleolus, and nucleus.

2. **Understand the Role of Each Component**:
- **Protoplasm**: This is the living substance of a cell, including the cytoplasm and the nucleus. While it is essential for life, it does not specifically control cell functions.
- **Cytoplasm**: This is the gel-like substance within the cell membrane that contains organelles. It plays a role in cellular processes but does not control the functions of the cell.
- **Nucleolus**: This is a structure within the nucleus that is involved in ribosome production. It is important but does not control the overall functions of the cell.
- **Nucleus**: This is known as the control center of the cell. It contains the genetic material (DNA) that encodes for proteins, which are essential for carrying out various functions in the cell.

3. **Determine the Correct Answer**: Since the nucleus contains the DNA that is responsible for encoding proteins, and proteins are crucial for the physiological functions of the cell, the nucleus is indeed the component that controls the functions of the cell.

4. **Conclusion**: Therefore, the function of the cell is controlled by the nucleus.

**Final Answer**: The function of the cell is controlled by the nucleus.
