2. **Components of Protoplasm**: Protoplasm can be divided into two main components:
- **Cytoplasm**: This is the jelly-like substance that fills the cell outside the nucleus. It contains various organelles and is involved in many cellular processes.
- **Nucleoplasm**: This is the fluid found inside the nucleus. It surrounds the chromatin and nucleolus and is involved in the processes occurring within the nucleus.

3. **Definition of Protoplasm**: Therefore, protoplasm is defined as the sum of cytoplasm and nucleoplasm. It represents all the living materials within a cell.

4. **Conclusion**: Based on the components of protoplasm, we can conclude that the protoplasm is the combination of cytoplasm and nucleoplasm.
