Transgenic plants are the ones -

  1. Produced after protoplast fusion in artificial medium
  2. Produced by a somatic embryo in artificial medium
  3. Generated by introducing foreign DNA into a cell and regenerating a plant from that cell
  4. Grown in artificial medium after hybridization in the field

Answer

(3) Generated by introducing foreign DNA into a cell and regenerating a plant from that cell

Solution

As per NCERT, plants whose genes have been altered by manipulation are called genetically modified organisms (GMO), i.e. transgenic plants.

A foreign gene is introduced into a plant cell and a whole plant is regenerated from that transformed cell.

Protoplast fusion gives somatic hybrids, and a somatic embryo gives a somaclone — neither carries a foreign gene.

Answer: (3)
