Tracheophytes are a group of vascular plants that have specialized tissues for transporting water and nutrients. This group includes familiar plants such as trees, shrubs, and flowering plants. They are characterized by the presence of xylem and phloem, which help in the movement of water, minerals, and food throughout the plant. Tracheophytes are divided into two main categories: seedless plants, like ferns and horsetails, and seed plants, which include gymnosperms and angiosperms. These plants play a crucial role in ecosystems, providing oxygen, food, and habitat for various organisms.
