The osmotic pressure is equivalent to …………………………… potential according to thermodynamics concept but opposite in sign of its value.

Explanation

**Step-by-Step Solution:**

1. **Understanding Osmotic Pressure**: Osmotic pressure is the pressure required to prevent the flow of water into an osmotically active solution through a semipermeable membrane. It essentially stops the movement of water.

2. **Direction of Water Movement**: Water moves from an area of lower osmotic pressure (or higher water potential) to an area of higher osmotic pressure (or lower water potential). This is important to understand the relationship between osmotic pressure and osmotic potential.

3. **Numerical Relationship**: According to thermodynamic concepts, osmotic pressure is numerically equal to osmotic potential. This means that if you know the osmotic pressure, you can determine the osmotic potential and vice versa.
