Which elements of xylem tissue form interconnected water-conducting channels?
Vessels and Xylem fibres
Tracheids and Xylem fibres
Only Vessels
Vessels and Tracheids
Vessels and Tracheids
Remember 'VT' for Vascular Transport: Vessels + Tracheids = Water Conduction.
Analyze Xylem Components
Xylem is a complex permanent tissue composed of four types of cells: tracheids, vessels, xylem parenchyma, and xylem fibres.
Identify Water-Conducting Elements
Both tracheids (elongated cells with pitted walls found in gymnosperms and angiosperms) and vessels (tube-like structures formed by dead cells joined end-to-end found mainly in angiosperms) are dead, hollow, tubular structures that join together to form continuous, interconnected channels for vertical water and mineral transport.
Evaluate Other Components
Xylem fibres provide mechanical support, while xylem parenchyma stores food and helps in lateral conduction of water.
