Does xylem vessels have nucleus?
Herein, does xylem vessel have cell membrane?
Xylem vessels are a long straight chain made of tough long dead cells known as vessel elements. The vessel have no cytoplasm. They are not living, but are made by living cells. They have a lignified cell wall and a central cavity.
Similarly, do mature cells of xylem have nucleus? Unlike xylem, phloem is alive at maturity, but usually with a much reduced cell contents and no nucleus.
Herein, do vessel elements have a nucleus?
Its elements are elongated, just like those of the xylem. In contrast to tracheids and wood vessels, mature phloem elements contain a protoplast and sometimes even a nucleus.
What are vessels in xylem?
The xylem vessels are long tubes which help in transportation of water and provide mechanical support. Each xylem vessel is formed by end to end union of a large number of short, wide, lignified dead cells. In these cells both the nucleus and cytoplasm are absent.
