Difference between Tracheids and Vessels
Characteristics |
Tracheids |
Vessels |
Structure | Elongated cells with tapered ends and a uniform diameter | Tube-like structures formed by the fusion of vessel elements |
Secondary cell wall | Thick and lignified | Variable thickness, less lignified |
Perforation plates | Absent | Present |
Water transport | Less efficient due to narrower diameter and absence of perforation plates | More efficient due to wider diameter and presence of perforation plates |
Distribution | Present in all vascular plants | Primarily found in angiosperms and a few specialized gymnosperms |
Evolutionary advancement | A less advanced form of water-conducting cells | More advanced forms associated with the success of angiosperms |
Difference Between Tracheids And Vessels
Difference Between Tracheids And Vessels: Tracheids and vessels are specialized cells involved in water conduction within plants. Tracheids are elongated cells with thick walls, while vessels are tube-like structures formed by fused cells. These contrasting adaptations allow plants to efficiently transport water and nutrients from roots to other parts of the plant.
