Options

A. solute particles from higher concentration to lower concentration
B. solvent particles from higher water potential to lower water potential through a semi permeable membrane
C. solute particles from higlter concentration to lower concentration through a semipermeable membrane
D. solvent particles from lower water potential to higher water potential.

Answer

**Step-by-Step Solution:**

1. **Understanding Osmosis**: Osmosis is a specific type of passive transport that involves the movement of water molecules (solvent) across a semipermeable membrane.

2. **Direction of Movement**: In osmosis, water moves from an area of higher water potential (where there is a higher concentration of water molecules) to an area of lower water potential (where there is a lower concentration of water molecules).

3. **Role of Semipermeable Membrane**: The movement occurs through a semipermeable membrane, which allows certain molecules (like water) to pass through while restricting others (like solute particles).

4. **Energy Requirement**: Osmosis does not require any energy input; it is a passive process driven by the concentration gradient of water.

5. **Conclusion**: Therefore, in osmosis, the solvent (water) moves from an area of higher water potential to an area of lower water potential through a semipermeable membrane.

**Final Answer**: Osmosis is the movement of solvent particles (water) from higher water potential to lower water potential through a semipermeable membrane.
