Question
Chapter 37.3, Problem 1CC
Summary Introduction
To describe: The change in phytochrome if a deeply buried seed were uncovered enough to receive sunlight.
Introduction: Photoreceptors are light sensors produced by plants in order to sense the direction and amount of light received for several plant activities which require the proper amount of light. Every photoreceptor has a light absorbing component along with regions that switch on signal transduction pathways when the light is absorbed. There are several types of photoreceptors such as blue-light receptors, phytochromes and so on.
