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

Options

A. Organ culture
B. Micropropagation
C. Macropropagation
D. Plantlet 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.

2. **Analyzing the Options**:
- **Option 1: Organ Culture**: This method involves isolating specific organs for in vitro growth. While it is a type of tissue culture, it does not specifically focus on producing a large number of plantlets.
- **Option 2: Micro Propagation**: This technique is an in vitro method that allows a single cell to regenerate into a large number of whole plants, which are referred to as plantlets. This option directly addresses the question.
- **Option 3: Macro Propagation**: This is a conventional method of vegetative propagation, which includes techniques like offset planting and rooting of cuttings. It is less effective in producing large numbers of plantlets compared to micro propagation.
- **Option 4: Plantlet Culture**: This refers to the culture of young plants but does not specify a method for producing them in large numbers.

3. **Identifying the Correct Answer**: After evaluating all options, it is clear that **micro propagation** is the correct technique for obtaining a large number of plantlets from a single cell.

4. **Conclusion**: The technique of obtaining a large number of plantlets by tissue culture method is called **Micro Propagation**.
