In this article we will discuss about the CO2 Fixation Pathways—C4 Cycle. In 1954, in addition to Calvin cycle, an alternative pathway for CO2 fixation in photosynthesis was discovered by Kortschak who reported the formation of C4dicarboxylic acids as primary products of photosynthesis in sugarcane. When 14CO2 was supplied to sugarcane leaves for a short period, 3 four carbon dicarboxylic [...]
Environmental factors greatly influence the structural and physiological adaptations of leaves in plants. Some of the factors like light, temperature and water greatly affect the structural and biochemical change in the leaf. Thus plants growing under forest canopy and deserts (Table 13-6) have different structural adaptabilities. Xerophytic plants have adaptations which help the plant to minimize water loss and at [...]
In this article we will discuss about the mechanism of photosynthesis in algae and leaves. Photosynthesis in Alage: Photosynthesis in Algae and Liverworts: Unicellular algae are aquatic and hence have abundant water and light available as raw materials. The third raw material CO2 is soluble in water and forms bicarbonate and carbonate. The solubility of CO2 in water is low [...]
