GMO plants contain which of the following?

GMO plants, or genetically modified organisms, are characterized by their modified genes. This genetic modification is accomplished through various biotechnology techniques that allow for the alteration of a plant's DNA to enhance certain traits. These traits can include herbicide resistance, which enables the crops to survive the application of specific herbicides that would normally kill them; this is particularly useful in managing weeds without harming the crop itself.

In addition, some GMO plants are engineered to produce natural pesticides, allowing them to fend off pests without the need for additional chemical pesticides. This trait can promote sustainable agricultural practices by reducing the reliance on synthetic chemicals.

Therefore, GMO plants can indeed contain all of these characteristics—modified genes, herbicide resistance, and natural pesticides—making the inclusive answer a comprehensive representation of the diverse traits that genetically modified plants can exhibit.
