Answer:
Advantages of genetically modified plants are - (i) Pest resistance - Crop losses from insects pests can be incredible, resulting in financial loss for farmers and starvation in developing countries. Growing GM foods such as BT corn, Bt cotton etc. can help eliminate the application of chemical pesticides & reduce the cost of bringing a crop to market. (ii) Disease resistance-There are many viruses, fungi & bacteria which causes plant diseases. Plant biologists are working to create plants with genetically engineered resistance to these disease. (iii) Cold tolerance - Unexpected frost can destroy sensitive seedlings. An antifreeze gene from cold water fish has been introduced into plants such as tobacco and potato. (iv) Nutrition - Generally, rice does not contain adequate amounts of all necessary nutrients to prevent malnutrition. If rice could be genetically engineered to contain all additional vitamins minerals, nutritional differences could be alleviated. Plants were underway to develop golden rice that a Whas increased iron content.
