In this article we will discuss about the Hatch-Slack (C4) pathway of co2 fixation. The discovery of C4 cycle in monocots such as sugarcane, maize and sorghum has indicated that these plants have solved the problem of photorespiration. The carbon dioxide is fixed in the mesophyll cells. The initial product being a-4 carbon compound, the process is called C4 pathway [...]
The following points highlight the ten major factors affecting photosynthesis. The factors are: 1. Light 2. Carbon-Dioxide 3. Water 4. Nutrient Supply 5. Temperature 6. Oxygen Concentration 7. Chemical Compounds 8. Chlorophyll Content 9. Leaf Anatomy 10. Protoplasmic Factors. Factor # 1. Light: A study of the effect of light on the rate and quantity of photosynthesis would have to [...]
In this article we will discuss about the Blackman’s law of limiting factor of photosynthesis. Sachs in 1860 for the first time propounded the concept of the three cardinal points. According to this concept, there is a minimum, optimum and maximum for each factor in relation to photosynthesis. This way, with any given species there may be a minimum temperature [...]
