Question

Which of the following statement is incorrect for "Genetically Modif
plants':-
(A) increase the reliance on chemical pesticides
(B) enhanced nutritional value of food
(C) increase efficiency of mineral usage by plants
D) made crops more tolerant to abiotic stresses (cold, draught, salt, heat)​

Answer 1

Answer:

increase the reliance on chemical pesticides

Explanation:

actually it reduces

Answer 2

ANSWER:

option A is incorrect.

EXPLANATION:

Genetically modified crops can reduce the reliance on chemical pesticides.

GENETICALLY MODIFIED CROPS:

• When the gene of a crop is altered to make it resistant to drought or harsh climatic conditions or to develop pesticide resistant is called genetically modified crops.

• Genetic modifications can also be done to animals to increase the production of milk in cattle or to increase the production of egg and increased meat content in poultry.

• Genetic modification in bacteria is also done. A superbug was developed by Anand Mohan Chakrabarthy ,which is a genetically modified Pseudomonas putida , to control the oil spills in ocean.

ADVANTAGES OF GENETICALLY MODIFIED CROPS:

• Genetic modifications help plant to develop resistance against insects and pests.

• They increase the nutritional value of food.

• It increases the efficiency of mineral usage by plants.

• It makes the crops tolerable to abiotic stresses like cold , drought conditions and also makes them viable in acidic and hot conditions too.

• It will reduce the reliance on chemical pesticides.

EXAMPLES :

• Golden rice , which is vitamin A enriched.

• Tobacco plants against nematode infection .

• Production of Bt crops by using Bt genes of Bacillus thuringensis
