Detailed explanation-1: -Tracheary elements of xylem tissue include tracheids and vessels. The main function that these elements perform is the ascent of sap. Tracheids differ from other tracheary elements in being imperforated. Tracheids possess imperforated cells thus, keeping the sap for a longer duration in them.

Detailed explanation-2: -Commonly vessel elements are considered “perforate” cells, whereas tracheids are considered a type of “imperforate tracheary element” in dicotyledons (along with libriform fibers and fiber-tracheids).

Detailed explanation-3: -Tracheids are made up of single cells, whereas vessels are made up of a group of cells. Tracheids can be found in all vascular plants, but vessels are only seen in angiosperms. Tracheids are small and narrow, whereas vessel components are large and wide.

Detailed explanation-4: -Tracheids are elongated cells in the xylem of vascular plants that serve in the transport of water and mineral salts. The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs.

Detailed explanation-5: -Tracheids are elongated cells in vascular plants that transport water and mineral salts through the Xylem. Tracheids are one of two tracheary element groups. The other category is vessel elements.
