Totipotency is the basic principle of

Options

A. Tissue culture
B. Silviculture
C. Sericulture
D. Pisciculture.

Answer

**Step-by-Step Solution:**

1. **Understanding Totipotency**:
- Totipotency refers to the ability of a single cell to divide and produce all the differentiated cells in an organism, including the extra-embryonic tissues. In plants, this means that a single plant cell has the potential to regenerate into a whole plant.

2. **Identifying the Context**:
- The question asks about the principle of totipotency in relation to various agricultural practices: tissue culture, silviculture, sericulture, and pisciculture.

3. **Analyzing Each Option**:
- **Tissue Culture**: This is a technique that utilizes the totipotency of plant cells. In tissue culture, cells are taken from a plant and grown in a controlled environment to produce new plants.
- **Silviculture**: This is the practice of managing forests and does not specifically rely on the principle of totipotency.
- **Sericulture**: This involves the cultivation of silkworms for silk production and is not related to plant cell totipotency.
- **Pisciculture**: This refers to the breeding and rearing of fish, which also does not involve plant cells.

4. **Conclusion**:
- Since tissue culture directly utilizes the concept of totipotency to regenerate whole plants from single cells, the correct answer to the question is **Tissue Culture**.

**Final Answer**: Totipotency is the basic principle of **Tissue Culture**.
