The xylem tube contain a ring of lignin which forms a spiral pattern around the xylem tube. The xylem is made up of water proof, dead cells; which enables it to have high capacity for transporting large quantity of water

Xylem cells are the long tubular cells that carry water and minerals from the roots of a plant to the rest of the plant. These cells are specialized for water transport and provide structural support to the plant.
Red blood cells are adapted for oxygen transport due to their concave shape and lack of a nucleus, allowing for more space to carry oxygen. Nerve cells are adapted for rapid transmission of electrical impulses with their long axons. Muscle cells are adapted for contraction with abundant mitochondria for energy production.
at first they do, but as they mature, their cell walls thicken and they get htese things called lignin that makes it harder and rigid. this help keep plant standing up, but also means water can't get into the xylem cells so they die, thus no nucelus.

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)

I think it's the Xylem. They absorb water from the roots, and run through the stem. Then, they carry the water in the vessels to the whole plants, and out through the plants through the leaves stomata.
Xylem cells are in plants not animals.
Xylem cells are found in vascular plants.
This is the vascular tissue xylem.
