How is Xylem tissue well adapted to its function?
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.
What is a woody tissue of a plant?
Xylem
How are xylem cells good at their job?
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
How are specialized cells of xylem and phloem suited for their functions?
Xylem vessels are adapted to carry out their function in several ways. Phloem Specialized cells called COMPANION CELLS are closely associated with the sieve tubes. Each contains a nucleus, numerous mitochondria and other organelles that are largely absent from the sieve tubes.
Long tubes that transport water from the roots to the leaves?
it's called "xylem" your welcome
How many types of elements together make up the xylem tissue?
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 have what?
Vascular plants have xylem
Write four elements of xylem?
Tracheids Vessels Xylem parenchyma Xylem fibres
What is trasported by the xylem?
Water is transported by the xylem.
Why it is called as xylem vessel but not xylem cell?
Because xylem is a vessel that water travels through.
What is the Xylem of a root?
the xylem is in the roots and the phloem is in the stem actually, their is xylem and phloem in the roots. there is a large central core of xylem often in the shape of an x. and the phloem is found in between the arms of the x shaped xylem.
Tubes that carry water and minerals in plants?
Xylem and Phloem exist both in the Plant's roots and it's upper parts.
