The group of cell initials for tissue culturing is called

Options

A. Callus
B. Hybrid
C. Sub-culture
D. Explant

Answer

To solve the question "The group of cell initials for tissue culturing is called," we need to analyze the options provided and understand the terminology related to tissue culture.

### Step-by-Step Solution:

1. **Understanding Tissue Culture**: Tissue culture is a technique used to grow cells, tissues, or organs in a controlled environment, usually outside of their natural environment. This process is essential for plant propagation and research.

2. **Identifying the Options**:
- **Callus**: This is a mass of unorganized plant cells that can be induced to grow in vitro. However, it is not the initial group of cells for starting tissue culture.
- **Hybrid**: This refers to the offspring resulting from the crossbreeding of two different plant species or varieties. It does not represent a group of initial cells for tissue culture.
- **Subculture**: This term refers to transferring cells from one culture medium to another to continue growth. It is a step in the tissue culturing process but not the initial group of cells.
- **Explant**: This term refers to a piece of tissue taken from a plant (like a stem, leaf, or root) that is used to initiate tissue culture. It is indeed the starting material for tissue culturing.

3. **Conclusion**: After analyzing the options, the correct answer is **Explant**. This is the group of cell initials used for tissue culturing.

### Final Answer:
The group of cell initials for tissue culturing is called **Explant**.
