Question

short note of structure and function of xylem

Answer 1

Answer:

Explanation:

The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels

Xylem also contains two other cell types: parenchyma and fibers.

In transitional stages of plants with secondary growth, the first two categories are not mutually exclusive, although usually a vascular bundle will contain primary xylem only.

The xylem is a conducting tissue in vascular plants. The xylem conducts water and mineral nutrients from the soil to various organs of the plant where such materials are used to manufacture foods. Complementing the xylem is the phloem that helps conduct the manufactured foods to the necessary parts of the plant. The xylem in some plants also perform supportive functions
