The technique of obtaining large number of plants through tissue culture is

Options

A. Micropropagation
B. Hybridoma technology
C. Cryopreservation
D. Totipotency

Answer

To answer the question regarding the technique of obtaining a large number of plants through tissue culture, we will analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding Tissue Culture**: Tissue culture is a method used to grow plants in a controlled environment, allowing for the propagation of plants from a small piece of tissue.

2. **Analyzing the Options**:
- **Micro Propagation**: This is a specific technique within tissue culture that involves the in vitro multiplication or regeneration of plant material under aseptic conditions. It allows for the rapid production of a large number of genetically identical plants from a small tissue sample.
- **Hybridoma Technology**: This technique is primarily used for producing large quantities of identical antibodies, not plants. It involves the fusion of a specific type of immune cell with a myeloma (cancer) cell.
- **Cryopreservation**: This method involves preserving living cells and tissues at very low temperatures. While it is useful for long-term storage of plant cells, it does not directly relate to the large-scale production of plants.
- **Totipotency**: This refers to the ability of a single cell to divide and differentiate into all types of cells in an organism. While it is a fundamental principle behind tissue culture, it is not a technique used for obtaining large numbers of plants.

3. **Conclusion**: Based on the analysis, the correct answer to the question about the technique of obtaining a large number of plants through tissue culture is **Micro Propagation**.

### Final Answer:
The technique of obtaining a large number of plants through tissue culture is **Micro Propagation**.
