Nucleus controls the activities of organelles and play a major role in heredity

Answer

**Step-by-Step Solution:**

1. **Understanding the Nucleus**: The nucleus is a membrane-bound organelle found in eukaryotic cells. It is often referred to as the control center of the cell because it houses the cell's genetic material.

2. **Genetic Information**: The nucleus contains DNA (deoxyribonucleic acid), which carries the genetic instructions necessary for the growth, development, functioning, and reproduction of all living organisms.

3. **Role in Heredity**: The DNA within the nucleus is inherited from the parents. This genetic material is responsible for passing traits from one generation to the next, thus playing a crucial role in heredity.

4. **Control of Organelles**: The nucleus regulates the activities of the cell by controlling gene expression. This means it dictates which proteins are produced, influencing the function of various organelles within the cell.

5. **Conclusion**: Therefore, the statement "the nucleus controls the activities of organelles and plays a major role in heredity" is correct. The nucleus indeed plays a vital role in both controlling cellular activities and in the transmission of hereditary information.
