From these families of curves, the limiting factor relationship can be secured for any value of the photosynthesis rate 2 in terms of previous work an equation has been derived for describing these relations between the intensity and co 2 concentration necessary to produce a definite amount of photosynthesis. Factors limit photosynthesis what environmental factors simultaneously limit photosynthesis explain the concept of saturation by applying conditions under which photosynthesis is not limited factors limit photosynthesis related posts:the battle of ap bactitrationsports.
#44 limiting factors in photosynthesis limiting factor is something present in the environment in such short supply that it restricts life processes three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature. 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 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. 1 extensive measurements have been obtained (a) relating photosynthesis and light intensity for a large range of co 2 concentrations and (b) relating photosynthesis and co 2 at different light intensitiesfrom these families of curves, the limiting factor relationship can be secured for any value of the photosynthesis rate.
Factors affecting photosynthesis photosynthesis is affected by several external and internal factors external factors affecting photosynthesis 1 light three characteristics of light (i) intensity (quantity) (ii) quality (wave length) and , (iii) duration significantly affect the rate of photosynthesis. By understanding the factors that affect the rate of photosynthesis they can do work to try and increase the rate of photosynthesis to increase the yield of a crop the three main things affecting the rate of photosynthesis are: light temperature carbon dioxide these three factors are called limiting factors. The ability of each factor to limit the rate of photosynthesis, regardless of the other factors, is what makes them limiting factors lesson summary photosynthesis is the process by which plants absorb sunlight and use it to transform carbon dioxide and water into glucose and oxygen the major limiting factors in this process are light intensity, temperature, and carbon dioxide levels. Factors limit photosynthesis what environmental factors simultaneously limit photosynthesis explain the concept of saturation by applying conditions under which photosynthesis is not limited.
Given other factors are limiting, the rate of photosynthesis follows vant hoffs rule between 6°c-30°c to 35°c ie, it doubles with each increase of 10°c. Only a change to the limiting factor will increase or decrease the rate of photosynthesis changing the other two will have no effect in addition to the three main factors above are other factors such as chlorophyll concentration, water and pollution. The major limiting factors for photosynthesis are light intensity, temperature, and carbon dioxide levels light intensity since photosynthesis cannot begin without light, it is the first limiting factor.
When co 2, light and other factors are not limiting, the rate of photosynthesis increases with a rise in temperature, over a range from 6°c to about 37°c above this temperature, there is an abrupt fall in the rate and the tissue dies at 43°c. Rate of photosynthesis: limiting factors limiting factors the main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature 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 purpose of this experiment is to observe the factors affecting the photosynthetic rate of leaves, which is measured in two ways firstly changing the light intensity, this will determine the rate of increase or decrease in photosynthesis.
1 extensive measurements have been obtained (a) relating photosynthesis and light intensity for a large range of co 2 concentrations and (b) relating photosynthesis and co 2 at different light intensities from these families of curves, the limiting factor relationship can be secured for any value of the photosynthesis rate 2. External factors affecting photosynthesis photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors according to the law of limiting factors, put forward by ffblackman in 1905, photosynthesis is limited by the most limiting factor. Quiz & worksheet - limits of photosynthesis quiz gain more knowledge about the factors that can influence the rate of photosynthesis by using the lesson called limiting factors of. Factors affecting the rate of photosynthesis the term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place this can be measured by the amount of glucose produced by a plant over a given time.
These three factors are called limiting factors in a process like photosynthesis which is affected by more than one factor, its rate is limited by the factor which is closest to its minimum value so at any point in time if one of the three factors is in low supply, this factor will be the limiting factor.
What factor most affects the rate of photosynthesis the main variables which affect photosynthesis are light, water, co 2 concentration and temperature on a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are rarely covered in discussion of this topic.
