Answer 1

Dear student
Vessels are more evolved than tracheids. They have end walls with perforation and cell lumen is larger in size as compared to tracheids.
Moreover vessels are more efficient in water conduction and are confined to angiosperms only whereas tracheids are present in Pteridophytes, Gymnosperms and angiosperms.
