Exempel på hur man kan använda TRACHEIDS i en mening

• Sap is the fluid transported in xylem cells (tracheids or vessel elements) or phloem sieve tube elements of a plant.
• The wood (softwood) of gymnosperms such as pines and other conifers is mainly composed of tracheids.
• Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant.
• The thallus contains specialised sclerotic cells in its ventral region that serve as conducting tissue, though these differ from true tracheids in both form and function.
• Hydroids have been found in some fossilised plants from the Rhynie chert, including Aglaophyton, where they were initially mistaken for xylem tracheids.
• As in Asteroxylon the vascular bundle in the stems was an exarch actinostele, with a star-shaped arrangement of tracheids of a primitive annular or helical type (so-called G-type).
• Stems without xylematic vessels, with tracheids, xylem rays heterogeneous, uni- and multi-seriate, branches clearly differentiated in unifoliate brachyblasts and macroblasts with distichous phyllotaxis (Tetracentron), with nodes (1-)3(-multi)-lacunar, with (1)3(−7) leaf stems.
• Some other former "rhyniophytes", such as Horneophyton and Aglaophyton, are placed outside the tracheophyte clade, as they did not possess true vascular tissue (in particular did not have tracheids).
• One other former rhyniophyte, Aglaophyton, is also placed outside the tracheophyte clade, as it did not possess true vascular tissue (in particular did not have tracheids), although its conducting tissue is more complex than that of the Horneophytopsida.
• Isolated vessels are scattered in this mass of tracheids, accompanied by tangentially arranged groups of libriform cells (uncommon, resembling phloem, but very slender and relatively thick-walled).
• Protoxylem tracheids have helical wall thickenings, whereas the tracheids of meta- and secondary xylem possess scalariform and/or bordered pits.
