Difference between tracheas and blood vessels

Main difference

As plants prepare their food, they have a specialized type of conductive cells that carry out the transport process in plants. Plants can be divided mainly into two types, depending on their conductor; vascular plants and non-vascular plants. Vascular plants are those that have specialized conducting cells, xylem and phloem, whereas non-vascular plants lack these tissues and are transported using the simplest tissues. The xylem tissue is responsible for transporting water from the roots to the other parts of the plant, while the phloem tissue transports food from the plant leaves to the other parts. The xylem tissue is mainly composed of two Cell types; The tracheids, which are the elongated cells, and the vessels, which are the shortest and widest cells. Tracheids are present in all vascular plants; in gymnosperms, they occur alone in the woody area of ​​the plant, while in angiosperms they are associated with vessels. On the other hand, vessels are typically found only in angiosperms.

Tracheids Ships
Shape size Tracheids are long, elongated cells. The vessels are wider and shorter cells.
Present Tracheids are present in all vascular plants; in gymnosperms, they occur alone in the woody area of ​​the plant, while in angiosperms they are associated with vessels. The vessels are typically found only in angiosperms.
Ability to retain water Tracheids have a higher surface / volume ratio compared to vessels, so they can resist gravity and have the ability to retain water. It lacks the ability to retain water.
Training Tracheids are formed by the division of individual individual cells. The longitudinal bundle of cells divides to form vessels.
Wells Tracheids are imperforate cells, which have large holes that are less numerous. The vessels have smaller wells that are multiple in number.
What are tracheids?

Tracheids are elongated, lignified cells located in the tissue layer of the xylem; they are present in all vascular plants. In gymnosperms, tracheids are found in the woody area of ​​the plant, while in angiosperms, they are associated with vessels. They are usually large cells with a pointed end without perforations. Its main function in plants is to transport minerals and water and provide mechanical support to the plant body. These cells are derived from individual individual cells and lack protoplasm like similar vessels. Tracheids have the highest surface-to-volume ratio compared to vessels, so they can resist gravity and have the ability to retain water. These are imperforate cells,

What are boats?

Vascular elements are the lignified cells present in angiosperm plants; they are surrounded by the parenchymal cell. These cells are located in the xylem of the plant, they are responsible for transporting the sap from the roots to the other parts of the plant and provide the necessary mechanical support to the body of the plant. These cells perform a function quite similar to that of tracheids, although they are absent in gymnosperms, whereas tracheids are present in both angiosperms and gymnosperms. With a large diameter and perforations, the glasses are comparatively the best water carrier due to the presence of perforations. The longitudinal bundle of cells divides into different portions from these vessels, thus varying in length. Even after dividing these vessels they associate with each other through the perforations, which makes them a tubular structure wider in diameter. These vessels are named according to their shapes due to the perforations, the vessel with a simple perforation is called a simple perforation, the vessel with a ladder perforation is called a scalariform perforation, the vessel with several round openings is called a formed perforation, and finally, The vessel with the net-shaped pattern is called the reticulated perforation.

Tracheids against vessels
  • Tracheids are elongated cells, while vessels are wider and shorter cells.
  • Tracheids are present in all vascular plants; in gymnosperms, they occur alone in the woody area of ​​the plant, while in angiosperms they are associated with vessels. On the other hand, vessels are typically found only in angiosperms.
  • Tracheids have a higher surface / volume ratio compared to vessels, so they can resist gravity and have the ability to retain water.
  • Tracheids are formed with the division of individual individual cells, on the other hand, the longitudinal bundle of cells divides to form vessels.
  • Tracheids are imperforate cells, which have large pits that are fewer in number, while vessels have smaller pits that are multiple in number.
