A vessel element or vessel member (trachea) is one of the cell types found in xylem, the water conducting tissue of plants. Vessel elements (tracheae) are typically found in flowering plants (angiosperms) but absent from most gymnosperms such as conifers.

Are gymnosperms vascular? Gymnosperms are seed-bearing vascular plants, such as cycads, ginkgo, yews and conifers, in which the ovules or seeds are not enclosed in an ovary. The word "gymnosperm" comes from the Greek word gymnospermos, meaning "naked seeds".

Do Pteridophytes have xylem vessels? The cells of the vascular strands in pteridophytes are mainly tracheids, sieve cells, parenchyma, and endodermal cells. The tracheids, which comprise the xylem, or water-conducting tissue, are normally long, narrow, and attenuated at the tips. Their secondary walls display ladderlike (scalariform) thickenings.

Where are xylem vessels found in a plant? Xylem can be found: in vascular bundles, present in non-woody plants and non-woody parts of woody plants. in secondary-xylem, laid down by a meristem called the vascular cambium in woody plants. as part of a stelar arrangement not divided into bundles, as in many ferns.

Is xylem parenchyma dead or alive? The xylem is composed of dead cells with thick, lignified secondary cell walls.
