Are xylem cells alive or dead?

the Xylem consists of NON - LIVING material, it was never alive and hence cannot be dead. A big reason is that they must be hollow. Unlike veins etc. where many cells make up a wider vessel wall, in the case of xylem, single rodlike cells become the miniscule tubes.
A.

What is the function of the xylem cell?

The basic function of xylem is to transport water from roots to shoots and leaves, but it also transports nutrients. The word "xylem" is derived from the Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout the plant.
  • What is the difference between the xylem and phloem?

    It has two separate chambers tracheids and vessels for transporting minerals and water. Phloem is also important as the xylem tissues for vascular system of plants. The main activity of this tissue is to transport nutrients and food from leaves to other growing parts of plants.
  • What is the function of the xylem vessels?

    Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. The xylem tracheary elements consist of cells known as tracheids and vessel members, both of which are typically narrow, hollow, and elongated.
  • Where is the xylem?

    Xylem is located in roots, stems and leaves of the plant and it transports water and minerals from plant roots to aerial parts. With phloem it forms vascular bundles. Dead cells in Xylem contribute to wooden parts of the plant.
B.

What is the function of the xylem?

Plants have two different types of transport tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots.
  • What absorbs water and minerals on the roots?

    Plants can only absorb soluble minerals (those that can dissolve in water). They absorb minerals dissolved in solution from the soil through their root hair cells. However, the concentration of minerals in the soil is very low.
  • How does the xylem work?

    Water from the roots is pulled up by this tension. At night, when stomata close and transpiration stops, the water is held in the stem and leaf by the cohesion of water molecules to each other as well as the adhesion of water to the cell walls of the xylem vessels and tracheids.
