factors that affect the rate of photosynthesis

Chlorophyll Content 9. Blackman in 1905 proposed the principle of limiting factor. (Refer to teaching notes.) ADVERTISEMENTS: The following points highlight the ten major factors affecting photosynthesis. The intention of this experiment was to investigate different factors that affect the rate of photosynthesis. Blackman's law of limiting factors - law F.F. The hypothesis was, as light intensity increases the rate of reaction will increase at a proportional rate. Factors affecting the rate of photosynthesis. d Change one factor that may affect the rate of photosynthesis, keeping all other factors the same as far as possible. It is the slowest of these reactions that determines the overall rate of photosynthesis. Leaf Anatomy 10. Light 2. Water 4. Protoplasmic Factors. Answer the follow-up questions that follow. The rate of photosynthesis increases as the temperature increases. Limiting factors The main factors affecting rate (process) of photosynthesis are light intensity, carbon dioxide concentration and temperature. As the concentration of NaHCO3 increases the rate of the reaction will also increase at a proportional rate. The law of limiting factors is expressed as: At any given moment, [â¦] Temperature 6. Click to see full answer. Water Water is a very important raw material for photosynthesis. It determines the rate of photosynthesis. Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. Repeat the count and calculate the mean rate of bubble production as before. If the amount of CO 2 increases up to 0.1%, the rate of photosynthesis also increases. The term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place. This topic is especially important to scientist and farmers. 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. T here are many factors that affect the rate of photosynthesis, and it very important to understand how each factor affects the rate of photosynthesis. Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, pH and intensity of light. This can be measured by the amount of glucose produced by a plant over a given time. 1.Carbon dioxide The amount of carbon dioxide in the atmosphere is 0.03%. Photosynthesis is one of the most remarkable biochemical processes found on Earth and allows plants to use sunlight to make food from water and carbon dioxide. Nutrient Supply 5. Light: A study of the effect of light on the rate â¦ According to this principle, when a process depends on number of factors its rate is limited by the pase of the slowest factor. The factors are: 1. Furthermore, what are three factors that affect the rate at which photosynthesis occurs quizlet? But, the rate of photosynthesis decreases, if the amount of CO 2 increases beyond 0.1%. e Leave for 2 minutes and then take counts of the number of bubbles produced in one minute. Factor # 1. External factors. However, the rate declines after the temperature reaches an optimal level (usually â¦ Carbon-Dioxide 3. Chemical Compounds 8. Name: Factors that affect the rate of Photosynthesis Directions: Read through the passage. Highlight important information to help you to keep track of important concepts in the reading. Factors Affecting Photosynthesis A limiting factor limits the rate at which a process can take place. 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. 2. Three main factors affect the rate of photosynthesis: Light intensity: Increasing light intensity will increase the rate of photosynthesis, until the maximum amount of light is being absorbed.The main photosynthetic pigment in green plants is chlorophyll, which absorbs red and blue wavelengths (explaining their green appearance). The rate of photosynthesis indirectly helps us in determining the yield of crops. Processes such as photosynthesis are made up of a series of small reactions. The main variables which affect photosynthesis are light, water, CO 2 concentration and temperature. Oxygen Concentration 7. There are internal factors like number, size, age and orientation of leaves, mesophyll cells and chloroplasts, internal CO â¦
