A sythetic seed consist of

Options

A. Somatic embryo without protecting capsule
B. Only sodium alginate capsule
C. Somatic embryo with capsule made with mercuric choride
D. Somatic embryo, nutrient medium and capsule made with sodium alginate

Answer

To answer the question "A synthetic seed consists of," we will analyze the options provided and understand the components of a synthetic seed.

### Step-by-Step Solution:

1. **Understanding Synthetic Seeds**:
- Synthetic seeds are artificially created seeds that are used for plant propagation. They are designed to mimic the properties of natural seeds.

2. **Components of Synthetic Seeds**:
- A synthetic seed typically consists of three main components:
- **Somatic Embryo**: This is the embryo formed from somatic cells (non-reproductive cells) through a process called somatic embryogenesis.
- **Nutrient Medium**: This provides the necessary nutrients for the growth and development of the somatic embryo.
- **Protective Coating**: This is usually made from materials such as sodium alginate, which protects the embryo and nutrient medium.

3. **Analyzing the Options**:
- **Option 1**: Somatic embryo without protecting capsule only sodium alginate capsule.
- This option is incorrect because a synthetic seed requires a nutrient medium along with the somatic embryo and protective capsule.
- **Option 2**: Somatic embryo with capsule made with mercury chloride.
- This option is incorrect because mercury chloride is not used for encapsulation in synthetic seeds.
- **Option 3**: Somatic embryo, nutrient medium, and capsule made with sodium alginate.
- This option is correct as it includes all the necessary components of a synthetic seed.

4. **Conclusion**:
- The correct answer is that a synthetic seed consists of a somatic embryo, a nutrient medium, and a capsule made with sodium alginate.

### Final Answer:
A synthetic seed consists of a somatic embryo, a nutrient medium, and a capsule made with sodium alginate.
