Osmosis is concerned with the movement of water only and cannot directly affect the movement of dissolved substances into the roots and through the plant.

Answer

**Step-by-Step Solution:**

1. **Understanding Osmosis**: Begin by defining osmosis. Osmosis is the movement of water molecules from an area of higher water concentration to an area of lower water concentration through a semi-permeable membrane.

2. **Movement of Water Only**: Emphasize that osmosis specifically pertains to the movement of water. It does not involve the movement of solute particles (dissolved substances) directly.

3. **Semi-Permeable Membrane**: Explain the role of the semi-permeable membrane in osmosis. This membrane allows water molecules to pass through while restricting the movement of solute particles.

4. **Impact on Solute Movement**: Clarify that while osmosis facilitates the movement of water, it does not directly influence the movement of dissolved substances. The transport of solutes occurs through other mechanisms, such as diffusion or active transport.

5. **Conclusion**: Conclude that the statement in the question is true. Osmosis is indeed concerned with the movement of water only and does not directly affect the movement of dissolved substances into the roots and through the plant.
