 Tracheid | short length, low flow rates but safer, and bordered pits for cavitation prevention |
| Vessels | rapid water movement, combine vessel elements to overcome length limitation |
| Angiosperm ring structure | 4 types |
| Type 1 | Diffuse porous, wide-single vessels, typical of lowland evergreen rainforest trees. Not high latitudes |
| Type 2 | Diffuse-porous, Narrow-vessel, typical in both evergreen tropical montane and temperate trees, and many deciduous temperate species. |
| Type 3 | Ring-porous,typical of seasonal climates in the N hemis. And subtropical/Mediterranean climates. |
| Type 4 | Different vessel size classes intermingled throughout growth ring.common in ecosystems of temperate and dry Mediterranean to dessert regions. 80-97% Dual strategy for transport |
