Which of the following conditions show that the embryo of a seed is entering the state of dormancy?
Dry weight of seed is increasing
Watercontent is reducing.
The general metabolic activity of embryo is slowing down.
oxygen consumption of seed is increasing.

Options

A. A and b only
B. A,B and D
C. B and D only
D. B and C only

Answer

To determine which conditions indicate that the embryo of a seed is entering a state of dormancy, we can analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Understanding Dormancy**:
- Dormancy is a state where the seed embryo is inactive or in a resting phase due to unfavorable environmental conditions. During this phase, growth is minimal, and the seed conserves energy and resources.

2. **Analyzing Each Condition**:
- **Condition A: Dry weight of seed is increasing**:
- The dry weight of a seed is generally stable and does not increase significantly during dormancy. It remains constant unless the seed is losing water rapidly. This condition does not indicate dormancy.

- **Condition B: Water content is reducing**:
- A reduction in water content is a clear indicator of dormancy. As seeds lose water, they enter a state of metabolic slowdown to conserve energy and resources. This condition supports the idea of dormancy.

- **Condition C: The general metabolic activity of the embryo is slowing down**:
- During dormancy, the metabolic processes of the seed slow down significantly. This is a typical response to unfavorable conditions, indicating that the embryo is conserving energy and not actively growing. This condition also supports the idea of dormancy.

- **Condition D: Oxygen consumption of seed is increasing**:
- Increased oxygen consumption typically indicates active metabolism and growth, which is contrary to the state of dormancy. In dormancy, oxygen consumption would decrease as metabolic activity slows down. Thus, this condition does not indicate dormancy.

3. **Conclusion**:
- Based on the analysis, the conditions that show that the embryo of a seed is entering a state of dormancy are:
- **B: Water content is reducing**
- **C: The general metabolic activity of the embryo is slowing down**

### Final Answer:
The correct options indicating that the embryo of a seed is entering the state of dormancy are **B and C**.
