Gm Crops - GCSE Biology Definition

Genetically modified (GM) crops are plants used in farming that have been changed in the lab to have certain qualities. Scientists alter the plant’s DNA to help it grow better, resist pests, tolerate harsh weather, or improve the nutritional value. For example, some GM crops are designed to survive against insects, so farmers don't need to use as many pesticides. These modifications can make the crops more efficient and can help produce more food. However, there is also debate about their safety and environmental impact. GM crops are an important topic in GCSE Biology as they involve understanding genetics and biotechnology.
