In corn which does not evolve co 2 during illumination there was little effect of increasing temperature on the rate of apparent photosynthesis the different response to temperature of co 2 evolution in light and in darkness support the earlier conclusion some effects of temperature and carbon dioxide concentration on photosynthesis of. Factors affecting photosynthesis the external factors would include the availability of sunlight, temperature, co2 concentration and water as a plant photosynthesises, all these factors will simultaneously affect its rate. First of all, the rate of photosynthesis will be the fastest in a tube with a soda water exposed to the sun light due to the fact that content of the carbon dioxide is higher than in the rest of samples.
The effects of burning carbon dioxide the main waste product of fuel we burn is carbon dioxide, which is thought to have been the main factor in the gradual rise of global temperatures of the last hundred years. In photosynthesis, cells take in carbon dioxide (co2) and water (h2o) by absorbing energy from the sun, and then the cells release oxygen (o2) and store glucose (c6h12o6) the formula of photosynthesis is. In the atmosphere, the concentration of carbon dioxide ranges from 03 to 04 % however, it is found that 01% of carbon dioxide in the atmosphere increases the rate of photosynthesis significantly.
The rate of photosynthesis depends upon several factors they may be external or internal some of the external factors are intensity and duration of sunlight, temperature, availability of co 2 , availability of water etc. The plants absorb carbon dioxide for photosynthesis through the same pores (called stomata) but when carbon dioxide levels are high, the leaf pores shrink this causes less water to be released. Factors affecting photosynthesis are either internal or external internal factors are 1 stomatal condition ( sunken stomata less photosynthesis) 2 amount of starch ( less starch more is rate of photosynthesis) external factors are 1 atmosphe. Photosynthesis is the process by which higher plants manufacture dry matter through the aid of chlorophyll pigment, which uses solar energy to produce carbohydrates out of water and carbon dioxide the overall efficiency of this critical process is somewhat low, and its mechanics are.
Outline the potential harmful effects of increased carbon dioxide concentration on the ecosystem and state one measure that could be taken to reduce the amount of carbon dioxide in the atmosphere (6. The atmospheric carbon dioxide concentration has risen from about 270 parts per million (ppm) before 1700 to about 355 ppm today climate changes, including a mean global surface temperature rise of between 28 and 52°c, have been predicted by five independent general circulation models (gcms) for. Moreover, photosynthesis entails combining carbon dioxide and water into simple sugars like glucose through the use of energy from the sun (editorial board, 2012, p51) in contrast, cellular respiration is the process through which cells are allowed to tap into the energy stored during photosynthesis. Previous ib exam essay questions: unit 6 outline the effect of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis 6 marks light: explain the role of water in photosynthesis 4 marks.
The purpose of this experiment is to test whether factors such as light intensity and level of carbon dioxide, will affect the rate of photosynthesis, which are the two most important variables in the photosynthesis process. Carbon dioxide included among the rate-limiting steps of the dark stage of photosynthesis are the chemical reactions by which organic compounds are formed by using carbon dioxide as a carbon source the rates of these reactions can be increased somewhat by increasing the carbon dioxide concentration. The rate of photosynthesis is affected by a number of factors including light levels, temperature, availability of water, and availability of nutrients if the conditions that the plant needs are improved the rate of photosynthesis should increase.
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. The reverse way from your question, (the effect of photosynthesis on global warming) is the obvious way that plants, through photosynthesis, help reduce global warming by taking carbon dioxide from the atmosphere, thereby reducing the concentration of co2 and decreasing the greenhouse effect. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation)this chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the greek φῶς, phōs, light.
Carbon dioxide – with water – is one of the reactants in photosynthesis if the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase again, at some. The chief external factors affecting the rate of photosynthesis are the light intensity, temperature and carbon dioxide concentration it should also be noted that water availability, chlorophyll concentration, oxygen concentration and environmental atmospheric pollutants such as ozone and sulfur dioxide could also affect the rate of. - photosynthesis is the process undergone by plants consisting of a series of chemical reactions that require four factors water, carbon dioxide, radiant energy and temperature using chlorophyll molecules to trap radiant energy from the sun resulting in the making of glucose and oxygen as bi-products. #44 limiting factors in photosynthesis carbon dioxide in photosynthesis co2 is a key limiting factor the usual atmospheric level of co2 is 003% in perfect conditions of water availability, light and temperature this low co2 level holds back the photosynthetic potential.
