Gramineae, commonly known as the Poaceae family, includes grasses that are vital to ecosystems and agriculture. This family encompasses a wide variety of plants, from small lawn grasses to large cereal crops like wheat, rice, and corn. Grasses are characterized by their hollow stems, narrow leaves, and unique flower structures. These plants play a crucial role in soil conservation and provide habitat for many species. Gramineae are also important for livestock grazing and are a primary food source for many herbivores. Their extensive root systems help prevent soil erosion and improve soil health.
