Which of the following is not a genetically modified crop plant
A.Golden Rice
B.Basmati Rice
C.Bt-corn
D.Flavr savr tomato
Solution
Genetically modified plant is a plant whose DNA is modified by genetic engineering methods to introduce a desirable trait in the plant which is not naturally present in the plant.
Complete answer:
-Rather than using chemical pesticides it is better to use plants whose genes are modified using genetic engineering due to which the plant can become resistant to its pest without using chemical pesticides.
-Genetically modified plants give a higher yield as compared to non-modified plants and also helps to increase the nutritional value of the plant.
Option A: Golden rice is a genetically modified plant and it is modified such that it produces beta carotene which produces vitamin A, Hence, very useful food for people with vitamin A deficiency. Therefore, this is the incorrect option.
Option B: Basmati rice is long and aromatic rice which is traditionally grown in India and is very healthy as it provides some important nutrients and is not genetically modified, Therefore, this is the correct option.
Option C: Bt-Corn is also a genetically modified plant which shows resistance to Bacillus thuringiensis bacteria, whenever this insect affects a genetically modified plant dies due to the toxin, Therefore, this is the incorrect option.
Option D: Flavr-savr tomato is also a genetically modified plant which is modified to increase its shelf life and prevent its early ripening. Therefore, this is the incorrect option.
Hence, the correct answer is Option B.
Note: There are many advantages of Genetically modified plants as we discussed above but along with that, it shows some disadvantages as well because GM plants are a threat to natural biodiversity, and production of genetically modified plants is very expensive and sometimes the genetically modified plants can be harmful to useful insects or organisms.
