The family Poaceae, commonly known as grasses, includes a wide variety of plants that are essential to many ecosystems. This family consists of over 10,000 species, ranging from small lawn grasses to large bamboo. Grasses are characterized by their narrow leaves and hollow stems, and they typically grow in clumps or tufts. Grasses play a crucial role in agriculture, providing staple crops such as wheat, rice, and corn. They are also important for soil conservation, preventing erosion, and supporting wildlife habitats. Many species are adapted to diverse environments, from wetlands to arid regions, making them a vital component of the Earth's flora.
