Tracheids are elongated cells present in the xylem of vascular plants which serve in the transportation of water and mineral salts. One of the two types of tracheary elements is tracheids and the other is vessels (which will be described further). Tracheids and Vessels have similar functions but we can spot the difference between tracheids and vessels. One is Tracheids that do not have perforation plates like vessels. Later in this article, a tabular chart will be used to differentiate between tracheids and vessels.
Talking about Xylem, it is one of the two types of transport tissues in vascular plants and phloem being the other. Xylem’s function is to transport water from roots to stems and leaves, it can also transport various nutrients.
Vessels in plants can be defined as elements found as one of the cell types found in xylem which is the water conducting tissue of plants. Vessels are found in angiosperms, also known as flowering plants but are absent from the most gymnosperms like conifers. Vessels transport water, nutrients and minerals through the plant and are vascular tissues.
So, it can be said that the xylem vessels and tracheids are the main elements that play major roles in water conducting in different kinds of plants. Both are tracheary elements and highly specialized cells that are devoid of protoplast when they mature. Also, are non-living which are elongated in shape with lignified cell walls. However, they differ in their diameter and the efficiency in their functions. More differences between tracheids and vessels are detailed below.

Difference Between Tracheids and Vessels
Similarities Between Tracheids and Vessels
Having discussed the differences between tracheids and vessel, let’s now know about their similarities which are listed below :
Tracheids and vessels, both are the two components of the xylem.
Both the elements are tubular cells.
Both of these are dead at maturity since they possess secondary lignification.
Both tracheids and vessels are present in both primary and secondary xylem.
Both tracheids and vessels function in water conduction along the stem and also provide mechanical support to the plant.
