👉 Xylems, also known as phloem or sapwood, are the outermost layers of plant tissue. They are responsible for transporting water and nutrients from the roots to the rest of the plant's tissues. Xylem tissue is composed primarily of xylan and lignin, which form the binding sites for enzymes that help in breaking down cellulose (the major component of wood) into simpler sugars. This process is essential for maintaining the structural integrity and strength of the wood.
