Plant piece used in tissue culture is called

Options

A. explant
B. endplant
C. transplant
D. callus

Answer

**Step-by-Step Solution:**

1. **Understanding Tissue Culture**: Tissue culture is a technique used to grow plants in a controlled environment, often in a laboratory setting. This method allows for the propagation of plants without the need for seeds.

2. **Identifying the Plant Piece**: In tissue culture, a specific part of the plant is utilized for the process. This part is crucial as it contains the necessary cells that can develop into a new plant.

3. **Meristematic Tissue**: The plant piece used in tissue culture is typically meristematic tissue. This type of tissue is responsible for the growth of new cells and is found in areas of the plant that are actively growing.

4. **Terminology**: The specific term used for the plant piece taken for tissue culture is called the "X-plant." This is the source plant from which the meristematic tissue is obtained.

5. **Process of Micropropagation**: The X-plant is placed in a nutrient medium with growth hormones, which encourages the growth of the meristematic tissue into a callus, and eventually into plantlets.

6. **Conclusion**: Therefore, the answer to the question is that the plant piece used in tissue culture is called the "X-plant."
