Plant genetic resources are like the special ingredients in a cake recipe. They are sets of genes found in different plants. To make a cake, a baker needs certain kinds of flour, sugar, butter and eggs. Similarly, to make plants with certain characteristics, like being extra tasty or being better at fighting off diseases, scientists need certain kinds of genes. Plant genetic resources are collections of these special genes, like a library of recipes for making different kinds of plants. By studying these recipes, scientists can create new plants that can help farmers grow food and medicine more easily, like recipes for making a healthier, tastier cake.
