Transgenic plants are the ones

Options

A. Grown on artificial medium after hybridisation in the field
B. Produced after protoplast fusion in artificial medium
C. Produced by somatic embryo on artificial medium
D. Generated by introducing foreign DNA into a cell and regenerating plant from that cell.

Answer

**Step-by-Step Solution:**

1. **Understanding Transgenic Plants**: Transgenic plants are genetically modified organisms (GMOs) that have had foreign DNA introduced into their cells. This DNA can come from different species, allowing for the expression of new traits.

2. **Analyzing the Options**:
- **Option A**: "Grown on artificial medium after hybridization" - This is incorrect because transgenic plants are not specifically defined by hybridization.
- **Option B**: "Produced after protoplast fusion in artificial medium" - This is also incorrect. Protoplast fusion is a technique used in plant breeding but does not define transgenic plants.
- **Option C**: "Produced by somatic embryo on artificial medium" - This option is incorrect as well. Somatic embryogenesis is a method of plant tissue culture but does not pertain to the definition of transgenic plants.
- **Option D**: "Generated by introducing foreign DNA into a cell and regenerated plant from that cell" - This is the correct definition of transgenic plants. The process involves the introduction of foreign DNA into a plant cell, which can then regenerate into a whole plant.

3. **Conclusion**: Based on the analysis of the options, the correct answer is **Option D**.
