GMO plants contain what?

GMO plants, or genetically modified organisms, contain genes that have been deliberately inserted from another organism through genetic engineering techniques. This process allows scientists to enhance certain traits in the plants, such as increased resistance to pests, improved nutritional content, or better tolerance to environmental stresses. By incorporating specific genes, researchers can introduce beneficial characteristics that may not be present in the plant's original genome.

The modification is a precise method of altering the plant's genetic makeup to achieve desired outcomes that contribute to agricultural productivity and sustainability. This uniqueness of GMO plants is what distinguishes them from traditional breeding methods, which rely on natural genetic variation and selection over generations.

While options related to more robust roots, higher water retention, and resistance to pests may sometimes be outcomes of genetic modifications, they do not accurately represent the defining characteristic of GMO plants. The key aspect here is the presence of foreign genes from other organisms that are intentionally added to confer specific traits.
