Which of the following term is not related to tissue culture ?

Options

A. Explant
B. Palindroma
C. Soma clones
D. Hybrid protoplast

Answer

**Step-by-Step Solution:**

1. **Understanding Tissue Culture**: Tissue culture is a technique in biological research where fragments of tissues from plants or animals are grown in a controlled, artificial environment. This method allows for the growth of cells, tissues, or organs in vitro (outside the organism).

2. **Analyzing the Options**:
- **Explant**: This term refers to a piece of tissue that is taken from a plant or animal and placed into a nutrient medium for culture. This is directly related to tissue culture.
- **Palaeondroma**: This term does not relate to tissue culture. In fact, it refers to a genus of spiders and has no connection to plant or animal tissue culture.
- **Soma Clones**: These are clones derived from somatic cells through tissue culture techniques. This term is also related to tissue culture.
- **Hybrid Protoplast**: This term refers to cells that have had their cell walls removed and can be fused to create hybrid cells. This process is often used in tissue culture.

3. **Identifying the Incorrect Term**: Among the options provided, "Palaeondroma" is the only term that does not relate to tissue culture. The other terms (explant, soma clones, and hybrid protoplast) are all associated with the techniques and processes used in tissue culture.

4. **Conclusion**: The term that is not related to tissue culture is **Palaeondroma**.
