Vessels are limited in growth, are joined end to end to form continuous tubular structures with perforations in their cross walls. Water and minerals are efficiently conducted through these perforations. Vessels are present in most of the angiosperms. Tracheids are elongated and non-perforated. They have only pit pairs, at the regions of union with other tracheids. Conduction of water and minerals is not as efficient as in vessels. Tracheids are found in most of the gymnosperms.
