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 the rate of photosynthesis
The surface temperature of the Earth varies from one location to the next due to a variety of factors, including the amount of sunlight reaching the ground and the amount of air that enters the atmosphere. Teaching notes An assumption being made in this experiment is that the gas bubbles being counted are only oxygen, and that production of oxygen is proportional to the rate of photosynthesis. Does water affect photosynthesis? This is because the enzymes involved in the chemical reactions of photosynthesis are temperature sensitive and destroyed at higher temperatures. There is no substitute for the sound of a spreitzer. Once the light energy has been absorbed, the second step in photosynthesis is the splitting of water molecules into hydrogen and oxygen atoms.
Give reasons to support your answer. How are protoplasmic factors affect the rate of photosynthesis? Plants produce less KuP in C, as they are more sensitive to CO in the bundle sheath cells. The rate of photosynthesis does not increase with higher temperatures for all plants. Coloured filters can be used, but these will affect light intensity by different amounts depending on the colour. For instance, if a graph is plotted of carbon dioxide against light intensity: The compensation point is the light intensity at which the rate of photosynthesis is equal to the rate of respiration. Light intensity is a major factor in the rate of photosynthesis, as it is the energy source that drives the process.
Refer to teaching notes. Protoplasmic Factor: Besides chlorophyll certain protoplasmic factors also influence the rate of photosynthesis. Prepare your answers and get ready to share your answers with the class. 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. Above this temperature, there is an abrupt fall in the rate and the tissue dies at 43°C.
What are three factors that affect the rate of photosynthesis quizlet?
Many crops such as tomatoes and lettuce give higher yield when grown in greenhouses. Optimum or saturation intensities may vary with different plant species e. For instance, with lower concentrations of the limiting factor e. Photosynthesis requires water in order to occur, and when there is a lack of water, the rate of photosynthesis is reduced. The intensity of light affects the rate of photosynthesis, as different intensities of light can lead to different photosynthetic rates. Ans: The three internal factors affecting photosynthesis are chlorophyll content of leaves accumulation of byproducts and internal structure of leaves. By increasing the availability of these nutrients, plants are able to grow more efficiently and produce higher yields.
Factors that affect the rate of photosynthesis and applications of photosynthesis
Thereafter, it remains constant over a wide range of CO 2 concentrations. Therefore, in this case, CO2 is the limiting factor. For example, it does not require any external inputs, such as fertilizers or pesticides. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase. The extent of photorespiration is reduced by systems that concentrate carbon dioxide in photosynthetic cells. As light intensity increases, photosynthesis begins to move at a faster rate. The angle of incidence, or the angle at which the light hits the organism, is also important, as different angles can lead to different intensities.
Light: The photosynthetically active region of the spectrum of light is at wavelengths from 400-700 nm. There are several ways that farmers can use photosynthesis to increase crop yields. We would also do well to bear in mind that if we remove the source of light, the rate of CO 2 fixation falls to zero immediately. In order for photosynthesis to be successful, a number of factors must be present, including light, carbon dioxide CO2 , water, and temperatures. When the light intensity is increased, then a higher concentration of CO 2 will be decomposed and the rate of photosynthesis increases till light again becomes a limiting factor.
With further research, photosynthesis could revolutionize the way we produce energy and create new treatments for various medical conditions. What are the external factors that affect photosynthesis?. Phosphoglycollate metabolized by a amino acid chain reaction involving glycine. What happens during photosynthesis 4th grade? How will photosynthesis affect oxygen levels? PGR5 and PGRL1 have a high chlorophyll fluorescence phenotype in mutant form due to high light intensities. What are the 5 factors that affect photosynthesis? Similarly, temperature also influences the light optimum, 30-35°C and dark respiration optimum 40-45°C. In the natural world limiting factors like the availability of food water shelter and space can change animal and plant populations.
The Three Main Factors That Affect The Intensity Of The Photosynthesis Reaction
Photosynthesis is a process by which plants, algae, and some bacteria convert light energy into chemical energy. When CO2, light, and other factors are not limiting, the rate of tissue decays rapidly, causing tissue to die at a temperature of 43C. A similar graph will be obtained if oxygen production is plotted against light intensity. Oxygen inhibits the photosynthesis of C3 plants at atmospheric CO2 concentration Varburg effect. What factors affect photosynthesis and cellular respiration? Beyond the optimum levels on both sides of the normal range, the enzymes are deactivated or destroyed and photosynthesis stops. Nishikawa Y, Yamamoto H, Okegawa Y, Wada S, N, Taira Y, Sugimoto The role of the The amount of heat, light intensity, carbon dioxide, water, oxygen, and chlorophyll in the air determines the degree to which the system functions.
