Xylem cells are not living plant cells. They die so that they can form the thin tubes that conduct water upward via capillary action.

∙ 7y ago''because the whole plant is dead'' <---- NO!
the actual answer is this:The lignin in the walls prevents much from diffusing into or out of the cell except via the small pits that remain, so not much can enter or leave, and as progressively more and more lignin builds up (strengthening the vessel) theres less ability for anything inside the cell to survive.Also, they need to be hollow to allow water to pass up them; organelles get in the way especially vacuoles. So they have to be empty thus dead for that.
Thirdly, the ends break down forming a continuous vessel, so if the xylem elements were alive they'd be in a bit of trouble.
Parenchyma cells of xylem are living.Other cells are dead due to lignin deposition

Is mature phloem tissue dead upon maturity?
No, they are usually living. It is the xylem tissue that is made mostly of dead cells.
Why is it impossible for the water conducting cells of xylem to carry on active transport?
The cells of the xylem that conduct water are not alive.
What types of Organelles are present in Xylem cells?
Vessels are types of advanced xylem cells that are found in angiosperms. An xylem is made up tracheids and both of these cells have pits so that water can move sideways in the stem.
Are the cells that move water in plants the xylem or phloem or cuticle or none of those?
Xylem.
What is a group of xylem cells called?
Vascular tissue
Is mature phloem tissue dead upon maturity?
No, they are usually living. It is the xylem tissue that is made mostly of dead cells.
Why is it impossible for the water conducting cells of xylem to carry on active transport?
The cells of the xylem that conduct water are not alive.
Do xylem cells undergo cell division?
No, xylem cells are "dead" cells and therefore do not undergo cell division.
What is a sentence for xylem?
Xylem cells are found in vascular plants.
Where is xylem found in the body?
Xylem cells are in plants not animals.
Do xylem and phloem tissues stay alive all the time?
No xylem die at maturity but phloem stays alive all the time the plant is alive.
Where are xylem cells found in the human body?
xylem cells are present in the plant coducting tissue called xylem. they aren't in human body anywhere.
Are xylem cells red or blue?
xylem cells are *~!BLUE!~* because of the presence of lignin
What are two functions of the xylem cells?
One is to transport the water and the minerals. The cells are adapted to this job because they do not contain cytoplasm so the water and minerals can travel through the xylem more easily. Two is to support the plant. Their walls have lignin (hard material)
What types of Organelles are present in Xylem cells?
Vessels are types of advanced xylem cells that are found in angiosperms. An xylem is made up tracheids and both of these cells have pits so that water can move sideways in the stem.
What are the xylem and phloem are separated by?
A layer of cambium cells separates the xylem and phloem tubes.
Why is xylem vessel referred to as mechanical tissue?
- Walls made from dead lignin cells, which waterproof and support walls even if water levels are low in plants. - Narrow tubes so water column doesn't break easily. - Pits in walls allow water to move from one cell to another.
