What is a Genetically Modified Organism (GMO)?
Options
- AA plant, bacteria, fungi or animal whose genes have been altered through natural processes
- BA plant, bacteria, fungi or animal whose genes have been altered by manipulation
- CA plant, bacteria, fungi or animal whose genes have not been altered
- DNone of the above
Correct answer
B. A plant, bacteria, fungi or animal whose genes have been altered by manipulation
Step-by-step solution
Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO). GM plants have been useful in many ways. Genetic modification has: (i) made crops more tolerant to abiotic stresses (cold, drought, salt, heat). (ii) reduced reliance on chemical pesticides (pest-resistant crops). (iii) helped to reduce post harvest losses. (iv) increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil). (v) enhanced nutritiona
