The piece of plant used in tissue culture is called

Options

A. explant
B. somaclone
C. inoculant
D. clone

Answer

To answer the question "The piece of plant used in tissue culture is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Tissue Culture**: Tissue culture is a technique used to grow plant cells, tissues, or organs in a controlled environment. It involves using a nutrient culture medium to support the growth of these cells.

**Hint**: Tissue culture is a method for growing plant tissues in a lab setting.

2. **Identifying the Source of Cells**: In tissue culture, the cells used for growth are derived from specific parts of the plant that are capable of regeneration. These cells are known as totipotent cells, which means they have the potential to develop into a whole plant.

**Hint**: Totipotent cells can develop into any part of the plant.

3. **Active Parts of the Plant**: The totipotent cells are typically taken from the active parts of the plant, which include roots, stems, leaves, and other living tissues that participate in the plant's metabolism.

**Hint**: Active parts of the plant are those involved in growth and metabolism.

4. **Term for Plant Piece Used**: The specific piece of plant that is used in tissue culture is referred to as "X-Plant." This term encompasses any part of the plant that is utilized for the purpose of tissue culture.

**Hint**: The term "X-Plant" is crucial for identifying the plant part used in tissue culture.

5. **Evaluating Other Options**: The other options provided in the question (Soma clone, inoculant, clone) do not refer to the piece of plant used in tissue culture:
- **Soma clone**: Refers to the plant produced from tissue culture, not the part used.
- **Inoculant**: Refers to a substance used in inoculation, not a plant part.
- **Clone**: Refers to genetically identical organisms, not specifically to the plant part used in tissue culture.

**Hint**: Understanding the definitions of other terms helps clarify why they are not the correct answer.

### Final Answer:
The piece of plant used in tissue culture is called **X-Plant**.
