The technique of obtaining large number plantlets by tissue culture method is called

Options

A. organ culture
B. micropropagation
C. macropropagation
D. pantlet culture

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the technique used to obtain a large number of plantlets through tissue culture methods.

2. **Identifying Key Terms**: The key terms here are "large number of plantlets" and "tissue culture method".

3. **Reviewing Options**: The options provided are:
- Organ culture
- Micropropagation
- Macropropagation
- Plantlet culture

4. **Analyzing Each Option**:
- **Organ Culture**: This involves culturing whole organs or tissues but does not specifically refer to the mass production of plantlets.
- **Micropropagation**: This is a specific tissue culture technique that allows for the rapid multiplication of plants, producing many plantlets from a small amount of plant tissue (explant).
- **Macropropagation**: This generally refers to traditional methods of propagation that involve larger plant parts and is not a tissue culture method.
- **Plantlet Culture**: This term is not commonly used in scientific literature to describe a specific technique.

5. **Conclusion**: Based on the analysis, the correct answer is **Micropropagation**. This technique allows for the generation of a large number of plantlets from a small piece of plant tissue through tissue culture methods.

**Final Answer**: Micropropagation
