Chapter 37, Problem 9TYPSS
Summary Introduction
To review:
A hypothesis to explain that small seeds must be exposed to red light before they germinate, while large seeds do not depend on red light to germinate.
Introduction:
The photosynthesis is the most important process carried out in the plants in the presence of sunlight. In this process, the light energy is converted into chemical energy. It provides the plant with energy to carry out its
