Chapter 34.3, Problem 2SB
Summary Introduction
To review:
Role of water properties by which transportation of xylem sap in a plant takes place.
Introduction:
Transportation of water in plants is important for the regulation of nutrients and minerals across the cell. There are several mechanisms through which water reaches the different parts of the plants from the roots.

Why is the ability of water molecules to form hydrogen bondsimportant for the movement of xylem sap?
Why can xylem transport water and minerals using deadcells, whereas phloem requires living cells?
