The term "plant modifications" refers to changes or alterations made in plants, either through natural processes or human intervention. These modifications can involve various aspects such as genetic engineering, selective breeding, and other techniques that aim to improve plant characteristics or adapt them for specific purposes. For example, scientists may modify a plant's DNA to make it resistant to pests or able to grow in harsher conditions. Alternatively, farmers might crossbreed different varieties of plants to create new strains with desired traits such as higher yield, better taste, or improved nutritional content. Overall, "plant modifications" encompass a wide range of practices that seek to enhance the qualities and uses of plants for human benefit.
