Brief introduction of Chapter 13 Photosynthesis in Higher Plants

All animals including human beings depend on plants directly or indirectly for their food. In our universe sun is the ultimate source of energy and green plants are organisms which can trap sunlight into chemical form to synthesise food.

Photosynthesis is the mechanism of plants by which they prepare carbohydrates using CO2 and water in the presence of sunlight and chlorophyll.

Photosynthesis is also an important reason for another reason as it releases O2 into the atmosphere.

In this chapter, you will see the contribution of different scientists in understanding photosynthesis. For instance, T.W Engelman created the first action spectrum of photosynthesis using green alga Cladophora.

In green plants, H2O is the hydrogen donor and is oxidised to O2. Some organisms do not release O2 during photosynthesis. When H2S, instead is the hydrogen donor for purple and green sulphur bacteria, the ‘oxidation’ product is sulphur or sulphate depending on the organism and not O2.

You will learn about the photosystem involved in light reactions. The dark reaction takes place in the stroma of chloroplast which involves the fixation of CO2 into carbohydrates.

Based on the primary product of CO2 fixation plants are categorised into C3 and C4 plants.

Photorespiration is a process found in C3 plants only. In this chapter, you will also get to know about different factors affecting the rate of photosynthesis.
