Osmotic pressure is the minimum pressure that has to be applied on the …………..to prevent that entry of………..from …………………….to……………… .

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Osmotic Pressure**: Osmotic pressure is a concept that arises when a solution is separated from a pure solvent by a semi-permeable membrane. This membrane allows the passage of solvent molecules but not solute particles.

2. **Identifying the Components**: In the context of the question, we need to identify the two sides of the semi-permeable membrane:
- One side contains the solution (which has solute particles).
- The other side contains the pure solvent.
