The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Osmosis**: Osmosis is defined as the movement of water molecules through a semi-permeable membrane from an area of higher water concentration (or lower solute concentration) to an area of lower water concentration (or higher solute concentration). 2. **Type of Transport**: Osmosis is a specific type of diffusion. While diffusion can refer to the movement of any substance, osmosis specifically refers to the movement of water. 3. **Passive Transport**: Osmosis is classified as a passive transport mechanism. This means that it does not require energy input from the cell; instead, it relies on the concentration gradient of water. 4. **Equilibrium**: The process of osmosis continues until equilibrium is reached, meaning that the concentration of water is equal on both sides of the semi-permeable membrane. 5. **Evaluating Options**: - Active transport requires energy and is not applicable to osmosis. - Secondary active transport also involves energy but is not relevant to osmosis. - Facilitated diffusion involves membrane proteins and is not the same as osmosis. - Therefore, osmosis is correctly identified as a specific form of diffusion. **Final Answer**: Osmosis is a specific form of diffusion. ---
