3 factors that affect the rate of photosynthesis Rating:
Photosynthesis is a process that occurs in plants and some other organisms, where energy from sunlight is used to convert carbon dioxide and water into glucose and oxygen. This process is essential for the survival of plants and for the functioning of the entire ecosystem. There are several factors that can affect the rate of photosynthesis, including light intensity, temperature, and the availability of water and carbon dioxide.
Light intensity: Light is an essential factor for photosynthesis, as it is the source of energy that drives the process. The rate of photosynthesis increases as the intensity of light increases, up to a certain point. However, if the light intensity becomes too high, it can actually inhibit photosynthesis. This is because too much light can cause the plant to produce more oxygen than it can use, leading to the breakdown of photosynthetic pigments and the death of the plant cells.
Temperature: The rate of photosynthesis is also affected by temperature. In general, photosynthesis occurs more quickly at higher temperatures. However, if the temperature becomes too high, it can inhibit photosynthesis. This is because high temperatures can denature the enzymes that are involved in the process, rendering them inactive.
Availability of water and carbon dioxide: Photosynthesis requires water and carbon dioxide in order to produce glucose. If the plant does not have access to sufficient amounts of these substances, the rate of photosynthesis will be slowed. Additionally, if the plant is experiencing drought conditions, it may not have enough water to support photosynthesis. Similarly, if the plant is growing in an area with low levels of carbon dioxide, it may not have enough of this substance to support photosynthesis.
In conclusion, the rate of photosynthesis is affected by several factors, including light intensity, temperature, and the availability of water and carbon dioxide. Understanding these factors can help us optimize the conditions under which plants grow and maximize their productivity.
Factors affecting photosynthesis
This energy is then transferred to the energy carrier molecule, ATP, which is used to power the reactions of photosynthesis. In nature the maximum rate of photosynthesis due to temperature is not realized, because light or CO 2 or both are limiting. By increasing the amount of energy available to the plants, increasing the availability of essential nutrients, and using supplemental lighting systems, farmers can increase the efficiency of photosynthesis and thus increase crop yields. According to Blackman and his colleagues, photoynthesis maintains a constant rate of reproduction over a wide range of CO2 concentrations after an optimum concentration has been reached. The external factors would include the availability of sunlight temperature CO2 concentration and water.
What are three factors that affect the rate of photosynthesis quizlet?
It is difficult to do this out in the open air but is possible in a greenhouse. This trait may be an ideal tool for manipulation in the aftermath of the next major global event, known as the second green revolution. The position of the compensation point is different from plants grown in brighter conditions. Another potential application of photosynthesis is in energy production. Photosynthesis can be used to increase crop yields, reduce the need for fertilizer, and improve the quality of crops.
While the process is already used to generate electricity, research is being conducted to determine its potential to produce biofuels. Water is required for photosynthesis to take place. Ethical issues Look out for small aquatic invertebrates attached to the pond weed used, and remove them to a pond or aquarium. At a certain carbon dioxide concentration, the rate of photosynthesis remain constant from point B to point C on the graph. Justify why you agree or disagree. Leaves having high chlorophyll content do not photosynthesize rapidly since they lack the enzymes or co-enzymes to use the products of the light reactions to reduce available CO 2. Another assumption is that all the bubbles are the same size.
If it is warmer, then the reaction will be more intense. But, beyond a certain limit, CO2 starts accumulating in the plant and this leads to slowing down of the process. The blue-green algae have action spectrum peak in yellow or orange light. These include Mg, Fe, Cu, CI, Mn, P and are closely associated with reactions of photosynthesis. Too much heat slows down photosynthesis, while too little heat causes it to slow down.
What factors can affect the rate at which photosynthesis occurs?
It is critical to understand how much light reaches the leaves in order to make photosynthesis work. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration. As you can see, there are many potential applications of photosynthesis in the real world. When the temperature rises, the rate of photosynthesis decreases more quickly. Among the most important factors that affect photosynthesis are temperature light intensity and the availability of water. Sometimes cutting 2—3 mm off the end of the weed will induce bubbling from the cut end, or change the size of the bubbles being produced. Check the Elodea to see if it is bubbling.
Factors that affect the rate of photosynthesis and applications of photosynthesis
Cyanobacteria genomes lack the pgrl1 gene, which has been shown in chloroplasts of plants32,33 and green algae39,40 to play a role in F-mediated CET. A survey of enzyme that use carbanionic intermediates was conducted in order to determine whether any of them consumed a significant amount of O2-containing substances. Assuming all other factors remain constant same amount of carbon dioxide and water , which plant will have a high rate of photosynthesis? In order for photosynthesis to be successful, a number of factors must be present, including light, carbon dioxide CO2 , water, and temperatures. It is observed that, when CO2 and light are not limiting factors, the rate of photosynthesis increases with increase in temperatures till the optimum level for that plant. What Factors Would Increase Photosynthesis? Farmers add additional carbon dioxide into the greenhouse to increase the concentration and so the rate of photosynthesis of the crops.
The Three Main Factors That Affect The Intensity Of The Photosynthesis Reaction
How do limiting factors affect photosynthesis? Oxygen: ADVERTISEMENTS: Oxygen has been shown to inhibit photosynthesis in C 3 plants while C 4 plants show little effect. Image by: slidesharecdn There are four factors that can affect the rate of photosynthesis: light, temperature, water, and carbon dioxide. As a result of the need for water conservation, land plants are limited in the amount of light they can absorb from the atmosphere by directly synthesizing photo-generation cells. Accumulation of Carbohydrates 15. The extent of photorespiration is reduced by systems that concentrate carbon dioxide in photosynthetic cells.
What are the five factors that affect photosynthesis?
The removal of water from the protoplasm also affects its colloidal state, impairs enzymatic efficiency, inhibits vital processes like respiration, photosynthesis etc. Plant Organelles: Compartmentation of Metabolism in Photosynthetic Tissues, by Hageman, R. The following are the ten major factors that affect photosynthesis. The plants in the CAM grow at night to convert CO into malic acid, which they then convert to C02 in the day to keep moisture levels stable. What are the internal factors of photosynthesis how do they affect photosynthesis? It takes 5 to 86-90 seconds to complete. In the process of increasing production, a rise in atmospheric carbon dioxide levels helps to sustain plant life.
