The term water potential was coined by

Options

A. Sayre
B. Von Mohl
C. Lloyd
D. Slatyer and Taylor

Answer

**Step-by-Step Solution:**

1. **Understanding Water Potential**: Water potential is a concept in plant biology that refers to the potential energy of water in a system compared to pure water. It is an important factor in understanding how water moves through plants.

2. **Definition of Water Potential**: Water potential is defined as the difference in chemical potential of water. This means it is the free energy per unit molar volume of water in a given system compared to its pure state.

3. **Conditions for Measurement**: Water potential is measured under specific conditions, namely at the same temperature and pressure. This ensures that the comparison is valid.

4. **Historical Context**: The term "water potential" was first introduced in the field of plant biology by specific individuals.

5. **Identifying the Coiners**: After reviewing the options provided (Seiry, Born-Moll, Loyd, Oertz, Sattler, and Taylor), it is noted that the term was coined by "Lathier and Taylor".

6. **Conclusion**: Therefore, the final answer to the question is that the term water potential was coined by Lathier and Taylor in the year 1900.

**Final Answer**: The term water potential was coined by Lathier and Taylor.
