Answer

To solve the question, "In a tissue culture pollen develops into a haploid plant. It is due to the property of," we need to analyze the options provided and understand the relevant biological concepts.

### Step-by-Step Solution:

1. **Understanding Tissue Culture**:
- Tissue culture is a technique used to grow plants from cells or tissues in a controlled environment. This method allows for the propagation of plants without the need for seeds.

**Hint**: Think about how plants can be grown from small parts, like cells or tissues.

2. **Identifying Key Terms**:
- **Totipotency**: This is the ability of a single cell to divide and produce all the differentiated cells in an organism, including the ability to form a complete plant.
- **Organogenesis**: This refers to the process of organ formation from undifferentiated tissues.
- **Parthenocarpy**: This is the development of fruit without fertilization, resulting in seedless fruits.
- **Test Tube Fertilization**: This is an artificial fertilization technique where fertilization occurs outside the organism, typically in a laboratory setting.

**Hint**: Focus on the definitions of each term and how they relate to plant development.

3. **Connecting Totipotency to Pollen Development**:
- In tissue culture, pollen grains can develop into haploid plants due to their totipotent nature. This means that the pollen grain, which is a single cell, has the capability to grow into a complete plant.

**Hint**: Consider how a single cell can give rise to an entire organism.

4. **Evaluating Other Options**:
- Organogenesis is not the correct answer because it specifically refers to the formation of organs, not the development of a whole plant from a single cell.
- Parthenocarpy does not apply here as it involves fruit development without fertilization.
- Test tube fertilization is related to fertilization techniques rather than the development of haploid plants from pollen.

**Hint**: Eliminate the options that do not relate to the development of a complete plant from a single cell.

5. **Conclusion**:
- Based on the definitions and the properties of the terms, the correct answer is **Totipotency**. This property allows pollen to develop into a haploid plant in tissue culture.

**Final Answer**: Totipotency
