Meristem culture is the culture of

Options

A. axillary or apical shoot meristems
B. anthers
C. plant seeds
D. young embryos

Explanation

**Step-by-Step Solution:**

1. **Understanding Meristem Culture**:
- Meristem culture refers to the technique of culturing the meristematic tissue of plants. Meristematic tissues are regions in plants where cells are actively dividing and can differentiate into various types of tissues.

2. **Purpose of Meristem Culture**:
- The primary purpose of meristem culture is to produce disease-free plants. The meristematic tissue is often isolated from diseased plants because it is typically not affected by the disease, allowing for the regeneration of healthy plants.

3. **Isolation and Growth Conditions**:
- In meristem culture, the meristem is isolated and grown under sterile conditions. This helps prevent contamination and ensures that the plant regenerated from the meristem is healthy.

4. **Identifying the Correct Option**:
- The question asks what meristem culture is the culture of. The correct answer involves identifying the type of meristem that is cultured.
- The options provided include various types of plant tissues. Among these, the axillary or apical shoot meristem is specifically used in meristem culture.

5. **Conclusion**:
- After analyzing the options, it is clear that the correct answer is the culture of axillary or apical shoot meristem. Other options such as plant seeds and young embryos are not utilized in meristem culture.

**Final Answer**: Meristem culture is the culture of axillary or apical shoot meristem.
