Xylem tissue is adapted for water transport with long, continuous tubes (vessels) lacking end walls and organelles for unobstructed flow. Lignin thickening provides support and prevents vessel collapse under tension, while pits allow lateral water movement around blockages.

| Front | Explain how xylem tissue is adapted for its function ( 4 marks) |
|---|---|
| Back | long cells / tubes with no end walls; continuous water columns; no cytoplasm / no organelles/named organelle; to impede/obstruct flow / allows easier water flow; thickening/lignin; support / withstand tension / waterproof / keeps water in cells; pits in walls; allow lateral movement / get round blocked vessels |
