Explanation:
Detailed explanation-1: -The water-conducting activity of the xylem relies on pipe-like structures consisting of cells called vessel elements. Xylem vessel elements have thick secondary cell walls (SCWs), which are composed of cellulose, hemicellulose, and lignin (Turner et al. 2007).
Detailed explanation-2: -Xylem tissue is made of four structural elements such as tracheid, vessels, xylem fibres, xylem parenchyma and rays. Each of these elements have their own individual functions and they work together to form the xylem.
