Step 1: Define pest-resistant plant:
A pest-resistant plant is one that has been genetically modified or bred to express a trait (often a toxin gene) that protects it from insect pest damage, reducing the need for chemical pesticides.
Step 2: Give an example:
Bt cotton is a pest-resistant plant, engineered with a cry gene from the bacterium Bacillus thuringiensis that produces a protein toxic to bollworm larvae.
Final Answer:
A pest-resistant plant resists insect attack; example - Bt cotton.
