Why do most of the plants that gives us cereal belong to the grass family?

Most cereal plants belong to the grass family (Poaceae) because grasses have evolved characteristics that allow them to thrive in diverse conditions and produce high yields. Their simple structure and efficient reproductive methods enable rapid growth and adaptation to various environments. Additionally, grasses have a high seed-to-plant ratio, making them particularly effective for agricultural purposes, which has led to their dominance in cereal production. This combination of traits has made grasses the primary source of staple foods worldwide.
