Chapter 39, Problem 3A
Summary Introduction
Introduction:
The direction of the feedback of the plant organs either in the direction of the light source or away from the light source is called phototropism. The movement of plant organs towards the light source is called positive movement and the movement of plant organs away from the light source is called negative movement.
