Plant materials refer to the various parts of plants that can be used for different purposes. This includes leaves, stems, roots, flowers, and seeds. These materials are essential in many industries, such as agriculture, construction, and textiles. For example, cotton is derived from the fibers of the cotton plant, while wood is sourced from trees for building and furniture. In addition to their practical uses, plant materials also play a crucial role in the environment. They help in photosynthesis, which is the process that allows plants to convert sunlight into energy. Furthermore, plant materials contribute to soil health and provide habitats for various wildlife.
