A Level Biology Revision "The Structure and Functions of Xylem"

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/...

In this video, we look at the structure and functions of xylem. First I show you how xylem vessels are formed and discuss the role of xylem vessels. We look at the function of lignin within the xylem vessel walls. We then look at xylem fibres and parenchyma cells.
