Question
Chapter 22, Problem 15WIO
Summary Introduction
To determine:
A hypothesis that describes that it is adaptive for a plant to flower in response to photoperiod instead of temperature.
Introduction:
Photoperiod is defined as the time of light exposure or day length that influences many aspects of a plant’s life. The plants respond in several ways to photoperiod, and all plants have a particular length of photoperiod during which they flower.
