Genetic modification of plants involves inserting segments of DNA into the chromosome to produce desired traits in the resulting plant.
Why Plants Are Being Genetically Modified
Commonly used to make plants resistant to insects and to herbicides.
Reduced use of toxic pesticides and herbicides means safer consumption for humans.
Improves the nutritional value of foods
Create crops which tolerate normally adverse growing conditions.
Other modifications help improve the shelf life of foods.
How Plants Are Genetically Modified to Produce Their Own Chemicals
Example of Crops That Are Genetically Modified
Herbicide resistant corn, soybeans, cotton, and canola
Pros and Cons of Genetically Modified Plants
Crops modified to produce pharmaceutically active products may inadvertently cross-pollinate food crops and people may unknowingly consume these pharmaceutical products.
