Plants are the primary source of food for all animals, which also includes human beings. This food, which the green plants need is made or synthesized by them through photosynthesis, and hence termed as autotrophs. This chapter's core is the process of photosynthesis in higher plants (green plants), which is defined as a physicochemical process, which consumes light energy to run the synthesis of organic compounds.
This chapter aims to make the students aware of the structure of the photosynthetic machinery and all those reactions that convert light energy into chemical energy. Photosynthesis in green plants is an indispensable process because of two reasons. The first reason is that it serves as the basis of existence for all known food chains on earth. The second reason is that through this process oxygen is released by the green plants into the atmosphere, which is the only survival instrument for all forms of life. Delve into the brief on the topics of this chapter to find out more about them.
Chapter 13 'Photosynthesis in Higher Plants' of class 11 Biology decodes the complex chemicals and reactions that play a vital part in changing the light energy into chemical energy when photosynthesis occurs in green plants, which have pigment chlorophyll present in them. In addition to this, the chapter also discusses the technicality (organization of photosynthetic machinery) of the photosynthesis process.
