Why is the cohesive property of water important in the ascent of water? What is âair bleedingâ and how does the structure of the bordered pits in vessels affect the spread of an air bubble in the xylem tissue? Compare and contrast xylem movement due to root pressure from that due to cohesion tension.
What is cavitation? And why is the redundancy of water transport vessels and tracheids important in maintaining the ability of a plant to provide water to its leaves essential?
