Genetically Modified Crops and Agriculture
Engineering Plants
Why Modify Crops
Plants can be engineered for traits such as pest resistance, disease resistance, improved nutrition, or tolerance to drought and other stresses.
Examples of Traits
A crop may be designed to resist insects, reduce food loss, or produce a nutrient that it normally makes in very small amounts. These changes aim to improve yield, nutrition, or sustainability.
Important Distinction
Genetically modified does not automatically mean harmful or beneficial. Each crop must be evaluated by its specific trait and evidence.
Possible Crop Traits
| Trait | Potential Benefit |
|---|---|
| Insect resistance | Less crop damage |
| Drought tolerance | Better survival in dry conditions |
| Improved nutrition | Higher levels of useful nutrients |
| Disease resistance | Reduced losses from pathogens |
Why might a farmer want a drought-tolerant crop?
Drought tolerance can help crops handle dry conditions.
Correct answer: To help the crop survive with less water
What is one possible reason to engineer a crop?
Some engineered crops are designed to improve nutritional value.
Correct answer: To improve nutrition
Name one trait that can be engineered into crops.
Other acceptable examples include drought tolerance, disease resistance, or improved nutrition.
Correct answer: Pest resistance.
Why is each genetically modified crop evaluated individually?
Different modifications can have different outcomes.
Correct answer: Because the safety and benefits depend on the specific trait and evidence.
