Chapter 39, Problem 11TYK
Summary Introduction
Introduction: The plants are a multicellular organism and belong to the kingdom Plantae. The environmental factors most essentially affecting the flowering time is the day-to-day period of light that is, photoperiod. The proteins that mediates transduction of light signal is photoreceptors.
