Recovery of healthy plants from diseased plants is possible through

Options

A. tissue culture
B. Pollen culture
C. Meristem culture
D. Ovary culture

Answer

**Step-by-Step Solution:**

1. **Understanding the Problem**: The question asks how we can recover healthy plants from diseased plants. The focus is on methods that can help in regenerating healthy plant tissues.

2. **Identifying the Key Concepts**: The key concepts here are:
- Diseased plants
- Healthy plants
- Recovery methods (tissue culture techniques)

3. **Exploring Tissue Culture Techniques**: There are several tissue culture techniques, including:
- Tissue culture
- Pollen culture
- Meristem culture
- Ovary culture

4. **Focusing on Meristem Culture**: Among these techniques, meristem culture is particularly important. The apical meristem (the growing tip of the plant) has a high division capacity and is rich in auxins, which are plant hormones that promote cell division.

5. **Mechanism of Meristem Culture**: The apical meristem can help in recovering healthy plants because:
- It has the ability to divide and form new cells.
- It can suppress the growth of viruses and diseases, as the new cells formed do not carry the viral infection.

6. **Conclusion**: Therefore, the recovery of healthy plants from diseased plants is possible through **meristem culture**.
