Xylem spirals in canned rhubarb are often more visible due to the cooking process during canning, which breaks down cell walls and makes the xylem structure more pronounced. In fresh rhubarb, the xylem is less noticeable because the plant's cells are intact and the fibrous structures are not as exposed. The canning process also softens the tissue, allowing the spirals to become more prominent. Thus, the difference is mainly a result of the physical and chemical changes during cooking.
The tracheids, fibres, and vessels present in the xylem, become lignified during development, losing their living contents. This makes the tissue impermeable (to water) so none is lost as water is transported via the xylem. The tracheids' bordered pits allow for the rapid movement of water from cell to cell. As is with tracheids, the lignification of vessels can occur as rings, spirals, scalariform or reticulate. In the first formed xylem, rings and spirals occur more frequently. This allows for a limited amount of stretching which may occur in young structures. Both tracheids and vessels provide a pathway for the transportation of water, whilst also contributing to support.
Yes xylem cells are hollow because Xylem are just made up from cell walls left from cells, making hollow tubes. The walls of these tubes are hydrophilic, so water attaches readily to them, helping it to climb on its way up the plant
Vascular plants have xylem
Water is transported by the xylem.
This is the vascular tissue xylem.
In Angiosperms , it is xylem vessels ( proto and meta xylem together ) , Xylem sclerenchyma and xylem parenchyma ; together form Xylem tissue ( That is why xylem is called a compound tissue ). In Gymnosperms , xylem vessels are replaced by Xylem tracheids . All other tings are almost the same .
Xylem cells are in plants not animals.
Xylem is a one way flow

Xylem is a type of plant tissue.
Xylem cells are found in vascular plants.
