Transgenic plants are
(a) produced by a somatic embryo in artificial medium
(b) generated by introducing foreign DNA in to a cell and regenerating a plant from that cell
(c) produced after protoplast fusion in artificial medium
(d) grown in artificial medium after hybridisation in the field
(b) The plants obtained through genetic engineering contain a gene or genes usually from an unrelated organism, such genes are called transgenes and the plants containing transgenes are known as transgenic plants. These plants are often called as genetically modified or GM crops, eg, Flavr savr tomatoes, golden rice. Plants are made transgenic for identification, expressing the gene activity in tune, to produce several chemicals like fatty acids, sugars, cellulose, rubber, etc.
