Nucleus is often described as "cell brain" because

Options

A. It is located in the centre of the cell
B. It is shaped like that of brain
C. It controls and coordinates various metabolic activities
D. It can divide and give rise to new nuclei

Answer

### Step-by-Step Solution:

1. **Understanding the Role of the Nucleus**: The nucleus is often referred to as the "cell brain" because it plays a crucial role in controlling and coordinating various functions within the cell. This includes overseeing metabolic processes and development.

2. **Evaluating the Options**:
- **Option A**: "It is located in the center of the cell."
- While the nucleus is typically centrally located in many cells, this does not explain why it is called the "cell brain." Therefore, this option is incorrect.
- **Option B**: "It is shaped like that of a brain."
- The shape of the nucleus does not resemble that of a brain, making this option incorrect as well.
- **Option C**: "It controls and coordinates various metabolic activities."
- This option accurately describes the function of the nucleus. It regulates cell functions, including metabolism and development, making it the correct choice.
- **Option D**: "It can divide and gives rise to new nuclei."
- While the nucleus can divide during cell division, this does not explain its role as the "cell brain." Thus, this option is also incorrect.

3. **Conclusion**: Based on the evaluation of the options, the correct answer is that the nucleus is often described as the "cell brain" because it controls and coordinates various metabolic activities.

### Final Answer:
The nucleus is often described as the "cell brain" because it controls and coordinates various metabolic activities (Option C).
