Dry seeds have a

Options

A. Highly negative water potential
B. Highly positive water potential
C. Zero water potential
D. Maximum water potential

Answer

### Step-by-Step Solution:

1. **Understanding Water Potential**:
- Water potential is defined as the free energy of water in a system, which influences the movement of water. It is measured in megapascals (MPa) and indicates how readily water can move from one area to another.

2. **Identifying Dry Seeds**:
- Dry seeds, also known as dormant seeds, have a very low water content. This low water content results in a low water potential.

3. **Water Potential Range for Dry Seeds**:
- The water potential of dry seeds typically ranges from about -350 MPa to -50 MPa. This indicates a highly negative water potential.

4. **Evaluating the Options**:
- Given the options:
- A) Highly negative water potential
- B) Highly positive water potential
- C) Zero water potential
- D) Maximum water potential
- Since dry seeds have a water potential that is highly negative, we can conclude that option A is correct.

5. **Final Answer**:
- Therefore, the correct answer is **A) Highly negative water potential**.
