Chapter 36.4, Problem 1R
Summary Introduction
To review:
The evidence indicating that plants contain a receptor for blue light.
Introduction:
Plants respond to different lights differently. This is possible due to the photoreceptors that are present on the surfaces. These receptors are the main sites for signal transduction that occurs after they receive light. The quality and quantity of light reaching these receptors determine the growth pattern of the plant.
