Learn the concepts of Class 11 Biology Photosynthesis in Higher Plants with Videos and Stories. This topic is especially important to scientist and farmers. The major limiting factors for photosynthesis are light intensity, temperature, and carbon dioxide levels.

There are several ways of measuring the rate of photosynthesis in the laboratory. A limiting factor limits the rate at which a process can take place. This can be measured by the amount of glucose produced by a plant over a given time. These include: the rate of oxygen. Processes such as photosynthesis are made up of a series of small reactions. You can follow any responses to this entry through the RSS 2.0 feed. Factors Affecting Photosynthesis. The term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place. In any given situation any one of these may become a limiting factor, in other words the factors that directly affects the rate at which photosynthesis can take place masking the effects of the other factors. The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. Factors affecting photosynthesis. output From the picture above, it is known that in the process of photosynthesis, plants require carbon dioxide, water, chlorophyll, and sunlight to produce carbohydrates (energy). Explain Blackman's law of limiting factors -( effect of carbon dioxide concentration, water,light intensity and temperature) on rate of photosynthesis.Discuss Refreshment of air by photosynthesis - experiment of priestly and von … According to this hypothesis, when a process is influenced by a number of factors, the rate of the process is limited by the slowest factor. These elements are the factors that affect … Describe internal and external factors of photosynthesis. At light intensities of 5.5 units and above, a carbon dioxide concentration of 0.1 per cent is limiting and the rate of photosynthesis does not increase even when light intensity is increased. The environmental factors affecting the process of photosynthesis follow the law of limiting factor as hypothesized by the British plant physiologist F. F. Blackman in 1905. Factors affecting the rate of photosynthesis. Factors Affecting Photosynthesis. Light Intensity. It is the slowest of these reactions that determines the overall rate of photosynthesis. To find out what are the factors that affect photosynthesis, first please consider the formula of photosynthesis rate in the image below!
