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 subject-matter and components of electron transport chain. Subject Matter of Electron Transport Chain: The primary function in photosynthesis is the raising of an electron to a higher energy level in chlorophyll. Then the electron is transferred to an acceptor. It is, as if, there is a hole in the chlorophyll which invites [...]
