Tracheids are specialized cells found in the xylem of vascular plants. They play a crucial role in transporting water and minerals from the roots to other parts of the plant. Tracheids are long, narrow cells with thick walls that help provide structural support, allowing plants to grow tall and withstand various environmental conditions. These cells are primarily found in gymnosperms and some angiosperms. Unlike vessel elements, which are another type of water-conducting cell, tracheids are more primitive and are characterized by their tapered ends. They facilitate water movement through a process called capillary action, ensuring that plants receive the necessary nutrients for growth.
