Chapter 23.2, Problem 2MC

Summary Introduction

To determine:

The path of water and dissolved minerals from the soil, into the root’s xylem, and up to leaves.

Concept introduction:

When water transport occurs through cytoplasm and vacuoles of the cell; the route which water have opted is termed as a symplastic pathway, whereas, when the water moves only through the xylem; the route of water transport is termed as an apoplastic pathway. Casparian strips which made up of an impermeable substance play a key role for water in switching to symplastic pathway from the apoplastic pathway.
