Exploring Photosynthesis: Autotrophs, ATP, and Key Discoveries in Plant Biology

This chapter delves into the essential concepts of photosynthesis, focusing on the role of autotrophs—organisms like plants that create their own food, contrasting them with heterotrophs that rely on consuming others for energy. It covers ATP's structure and function, including how energy is released during its usage. Key historical experiments by scientists such as Jan van Helmont, Joseph Priestley, and Jan Ingenhousz are highlighted, illustrating the foundation of our understanding of how plants utilize light, water, and carbon dioxide to thrive.
