Osmosis is the passage of water through a ...................... membrane from …………...... concentration of water molecules to ……………………… concentration

Explanation

**Step-by-Step Solution:**

1. **Understanding Osmosis**: Osmosis is a specific type of diffusion that involves the movement of water molecules. It is important to note that osmosis occurs through a membrane that selectively allows certain substances to pass through.

2. **Identifying the Membrane**: The membrane involved in osmosis is a **semipermeable membrane**. This type of membrane allows the passage of water while restricting the movement of solutes.

3. **Concentration of Water Molecules**: In the context of osmosis, we need to consider the concentration of water molecules. Water moves from an area of **higher concentration of water molecules** to an area of **lower concentration of water molecules**.
