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 need to analyze each of the provided statements carefully.

### Step-by-Step Solution:

1. **Understanding Dormancy**:
- Dormancy in seeds refers to a state where the seed does not germinate even under favorable conditions. This is characterized by a lack of metabolic activity and growth.

2. **Analyzing Each Condition**:
- **Condition 1: Dry weight of seed is increasing**:
- An increase in dry weight does not indicate dormancy. It may suggest that the seed is still accumulating nutrients or reserves, which can happen during active growth.
- **Conclusion**: This condition does not indicate dormancy.

- **Condition 2: Water content is reducing**:
- A reduction in water content can lead to a state where the seed cannot germinate. Seeds often lose water during dormancy, leading to a decrease in metabolic activities.
- **Conclusion**: This condition indicates that the seed is entering dormancy.

- **Condition 3: The general metabolic activity of the embryo is slowing down**:
- A decrease in metabolic activity suggests that the embryo is not actively growing or developing, which is a characteristic of dormancy.
- **Conclusion**: This condition indicates that the seed is entering dormancy.

- **Condition 4: Oxygen consumption of seed is increasing**:
- Increased oxygen consumption typically indicates active metabolism and growth, which is contrary to the state of dormancy.
- **Conclusion**: This condition does not indicate dormancy.

3. **Final Assessment**:
- From the analysis, we find that conditions 2 (water content is reducing) and 3 (general metabolic activity of the embryo is slowing down) indicate that the embryo of a seed is entering a state of dormancy.

### Answer:
The correct answer is that the conditions showing that the embryo of a seed is entering the state of dormancy are:
- Water content is reducing.
- The general metabolic activity of the embryo is slowing down.
