The functions of cell organelles are controlled by which component of the cell?

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding Cell Organelles**: Begin by recognizing that cell organelles are specialized structures within a cell that perform distinct functions necessary for the cell's survival and operation.

2. **Identifying the Control Center**: Among the various components of a cell, it is essential to identify which part regulates the activities of these organelles.

3. **Options Analysis**: The options provided are:
- Protoplasm
- Cytoplasm
- Nucleus
- Tissue

4. **Evaluating Each Option**:
- **Protoplasm**: This term refers to the living content of a cell, including the cytoplasm and the nucleus, but it does not specifically control organelle functions.
- **Cytoplasm**: This is the jelly-like substance within the cell membrane, where many organelles are located, but it does not control their functions.
- **Nucleus**: This is the control center of the cell, containing genetic material (DNA) and is responsible for regulating cell activities, including the functions of organelles.
- **Tissue**: This is a group of cells working together, not a component of a single cell.

5. **Conclusion**: The nucleus is the component that controls the functions of cell organelles. It plays a crucial role in processes such as protein synthesis, cell division, and cell differentiation.

### Final Answer:
The functions of cell organelles are controlled by the **nucleus**.
