Question

Bt cotton is resistant to:

• A. Bacteria
• B. Fungi
• C. Insects
• D. Nematodes

Answer 1

Answer:

C. Insects

• Bt cotton is resistant to insects. Bt cotton is genetically modified by inserting genes from Bacillus thuringiensis (Bt), which produce proteins toxic to specific insect pests like lepidopteran larvae (bollworm, tobacco budworm). This modification targets chewing insects but does not provide resistance against bacteria, fungi, or nematodes.
