Short, wide water-conducting cells in flowering plants that are joined end-to-end to form continuous tubes called vessels. Unlike tracheids, their end walls are perforated or completely dissolved, allowing efficient water flow.
From Latin 'vasculum' meaning 'small vessel' and 'elementum' meaning 'component.' The term developed in the early 20th century as microscopy revealed these specialized cells that form tube-like structures more efficient than tracheids.
Vessel elements are like plant plumbing that got a major upgrade! While tracheids are like drinking through a straw with tiny holes, vessel elements connect to form perfect pipes - it's why flowering plants conquered the world with their superior water transport system.
