Poaceae, commonly known as the grass family, is a large and diverse group of flowering plants that includes many familiar species such as wheat, rice, and corn. This family plays a crucial role in ecosystems and agriculture, providing food and habitat for numerous organisms. Grasses are characterized by their hollow stems, narrow leaves, and unique flower structures. They thrive in a variety of environments, from prairies to wetlands, and are essential for soil conservation and carbon sequestration. The economic importance of Poaceae cannot be overstated, as they are a primary source of food for humans and livestock alike.
