Summary Introduction

To write:

The environmental signal that roots use to achieve downward growth.

Introduction:

The root has a complex system whose main function is to anchor the plant to the soil and help in absorbing nutrients and water from the soil. The development of root is in coordination with the shoot system, which is influenced by the environmental conditions prevailing. Auxin is an important plant hormone that plays a pivotal role while working in coordination with water and nutrient supplies.
