In a tissue culture nedia, the resource of the phytohormone is:

Options

A. agar agar
B. glucose
C. micronutrients
D. coconut milk

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the source of phytohormones in tissue culture media. Phytohormones are plant hormones that play a crucial role in plant growth and development.

2. **Identifying the Components of Tissue Culture Media**: Tissue culture media typically contain various components that support plant growth, including solidifying agents, energy sources, and nutrients.

3. **Evaluating the Options**:
- **Agar Agar**: This is primarily a solidifying agent used in tissue culture media. It does not provide phytohormones.
- **Glucose**: This is an energy source for the growing plant cells but does not contain phytohormones.
- **Micronutrients**: While essential for plant growth, they do not serve as a source of phytohormones.
- **Coconut Milk**: This is known to contain phytohormones, particularly cytokinins and auxins, which are beneficial for plant growth in tissue culture.

4. **Conclusion**: Based on the evaluation of the options, the correct answer is that coconut milk serves as the resource of phytohormones in tissue culture media.

5. **Final Answer**: The resource of phytohormones in tissue culture media is **Coconut Milk**.
