The protoplasm of the cells is nothing but water in which different molecules are dissolved and several particles are suspended.

Answer

**Step-by-Step Solution:**

1. **Understanding Protoplasm**: Protoplasm is the living content of a cell that is surrounded by a plasma membrane. It consists of cytoplasm and the nucleus.

2. **Composition of Protoplasm**: The primary component of protoplasm is water, which makes up about 85-90% of its total composition. This water is crucial for various cellular processes.

3. **Forms of Water in Protoplasm**: Water in protoplasm exists in two forms:
- **Free Water**: This is the water that is not bound to any molecules and serves as a medium for biochemical reactions.
- **Bound Water**: This water is associated with other biomolecules, such as carbohydrates and proteins, and is not available for biochemical reactions.

4. **Role of Water**: The free water provides a medium for biochemical reactions, while the bound water is involved in maintaining the structure and function of biomolecules.

5. **Suspended Particles**: In addition to water, protoplasm contains various molecules and particles that are either dissolved or suspended. These include ions, organic compounds, and macromolecules that are essential for cellular functions.

6. **Conclusion**: Based on the understanding of protoplasm, the statement "The protoplasm of the cells is nothing but water in which different molecules are dissolved and several particles are suspended" is true. Water is indeed the major component, and it serves as a medium for biochemical reactions and a suspension medium for other cellular components.

**Final Answer**: True.
