Chapter 36, Problem 8TYU

Summary Introduction

To review:

Importance of exclusion of some ions by the plant and list down the differences between active and passive exclusion.

Introduction:

The uptake of ions in plants is performed through the roots. The minerals are transported via the xylem, whereas some of the ions make their entry out of the xylem for the cell as it requires them. The mineral transport across the plasma membrane is done by the chemiosmotic mechanism.
