what are the 4 factors that affect photosynthesis?

4. List any factors that you think may affect the rate of photosynthesis. Factors that affect the rate of photosynthesis The main variables which affect photosynthesis are light, water, CO 2 concentration and temperature. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. 7. Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. 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. (ii) Protoplasm – Dehydration of protoplasm reduces the rate of photosynthesis. Factors affecting Photosynthesis Let us understand about Photosynthesis Photosynthesis is a process by which, the autotrophic organisms use light to make sugar and O 2 (oxygen) from C O 2 (Carbon Dioxide) and H 2 O (Water). Photosynthesis is very important for life on Earth.Green plants build themselves using photosynthesis. This video looks at 3 factors that will affect the rate of photosynthesis. 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. Consider environmental factors that you could manipulate during the lab. Actually, this isn’t a big deal and you’re going to learn #4 simple methods to test and prove the requirement of above 4 factors. 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. Any change in the level of a limiting factor will affect … Between the temperatures of 0oC and 25oC the rate of photosynthesis is approximately doubled for each 10oC rise in temperature. If you’re a school science student, then almost all the time your exam will ask you to write how to test for the photosynthesis factors. 6. The sugars are used by the cell as energy, and to build other kinds of molecules. Limiting factors In 1905, when investigating the factors affecting the rate of photosynthesis, Blackmann formulated the Law of limiting factors. This states that the rate of a physiological process will be limited by the factor which is in shortest supply. This causes their stomata to close. The factors are: 1. Other factors that affect the rate of photosynthesis are the light intensity, the amount of chlorophyll and other color pigments in a plant, and the color of light. There are many factors that can affect photosynthesis. Experiments to Test Factors of Photosynthesis. 5. Provided that other factors are not limiting, the rate of photosynthesis increase in direct proportion to the temperature. The following points highlight the ten major factors affecting photosynthesis. Based on the equation, it's probably not surprising that carbon dioxide and sunlight are two major factors that affect photosynthesis, but there is a third that isn't so obvious: temperature. There are three internal factors and four external factors which affect photosynthesis : Internal factors (i) Chlorophyll – Nutritional deficiencies of mineral cause loss of chlorophyll, and hence the drop in trapping solar energy which reduces the rate of photosynthesis. in many plants, the optimum temperature is 25oC above which the rate levels off and then declines - largely as a result of enxyme denaturation. Instead of carbon dioxide, what will be used as the reactant in this lab? How will air return to these spaces? Since water is used in photosynthesis, even a slight change in the amount of water can change the amount of oxygen and carbon dioxide release from a plant. Similar to any other chemical reaction, the rate of photosynthesis can be determined by either measuring the decrease of its reactants or … Themselves using photosynthesis approximately doubled for each 10oC rise in temperature photosynthesis, Blackmann formulated Law.
