How Does Light Intensity Increase The Rate Of Photosynthesis

Improved Essays
Light intensity:
As the light intensity increases the rate of photosynthesis also increases as this is helping the chloroplast to absorb chlorophyll. However, when it reaches its optimum level the level stays the same.
Moreover, the Carbon dioxide concentration levels allows the plant to create food quicker. Once the Carbon dioxide reaches its optimum level the rate of photosynthesis stays the same.
In addition, at the start, when the temperature begins to rise the rate of photosynthesis rises with it although after it reaches its optimum we see a dip as the heat causes the enzymes involved in photosynthesis denatured (this means that the enzymes die).

An explanation of the economics of increasing the rate of photosynthesis in commercial

The way they work is that the fossil fuels are burnt which produces carbon dioxide whilst the plants can benefit from the heat that comes of off it. This isn’t good as it means that greenhouse gases are let in to the atmosphere. These cause global warming and climate change.
The third, blinds are accommodating because as we know that when the temperature increase the rate of photosynthesis rises with it. But when the temperature gets to high the enzymes become denatured. So these blinds make sure the level of heat doesn’t get too high in summer.
Method four brings us on to computer controlled systems. These may seem very sophisticated and are however this means that all the important factors that affect photosynthesis are able to be controlled whatever the weather outside. A disadvantage is it uses electricity which cannot be good for the environment and not all farmers have expertise in computing.
Liquid Carbon dioxide. Yes, you guessed it the carbon dioxide is liquidised. As a result, the Carbon dioxide can be pumped in to the greenhouse whenever needed. Unfortunately, it costs £7000 per year per greenhouse.
Propane burners increase the heat and carbon dioxide levels. It costs £30200 all together to install and to

    Photosynthesis Project Photosynthesis is like a squirrel that saves acorns for winter. This squirrel’s name is Chester. Chester must use his skills and some of his energy to go out and save up acorns for winter, which will provide him with energy when he needs it. He must expend some energy now to gain more energy in the future. The acorns he saves will later be broken down (eaten), and used for energy.…

    Introduction Carbon dioxide plays a huge rule on plant growth. This reports points out some positive affects as well as negative aspects of carbon dioxide concentration illustrated through a graph from the three trails. Some positive affect is that if a plant is receiving an average amount of CO2 and water and sunlight, it’ll have a positive affect depending on the type of the plant. The negative affect is if there is an imbalance of one element or if the plant if receiving too much or too little, for example if carbon dioxide in the atmosphere is too high then plants lose water due to the evaporation as the heat increases, also the excess CO2 in plants causes the plant to be less nutrient for human and animal consumption (Zhu 2005). However, the effect of carbon dioxide concentrations varies depending on the type of plant since each plant has different feedback affect and how the plant reacts to the increased level of CO2.…

    Plants change the sunlight's energy into chemical energy by the process of photosynthesis. Pigments in the plants called chlorophyll, absorb photons from the sun. Glucose is the main source nutrition in plants. Two reactions happen in the Photosynthesis that are the light reactions, also known as light dependent reactions, and dark reactions, also known as light independent reactions. The dark reactions are sometimes called the Calvin cycle, C3 Cycle, or Carbon Fixation.…

    As explained in the Results section, there is very clearly a correlation between temperature and rate of photosynthesis - being how quickly the leaves underwent photosynthesis, and floated to the top of the solution. The higher temperatures rapidly achieved 100% floatation, while the lower temperatures had very low floatation rates. Consequently, the hypothesis has been supported by the experiment. This can be explained by the differences in the movement of molecules betwixt each scenario. In the hot scenarios, the molecules would be moving around rapidly, causing there to be a much greater chance of enzyme-substrate interaction, as well as allowing the enzyme to carry out its process much more quickly.…

    This process is carried out in chlorophyll, a green pigment present in plants, some bacteria and some prostists4. Photosynthesis occurs in two stages, a light-dependent process (light reactions) and a light-independent process (dark reactions). During the light reactions, electrons in chlorophyll a are excited to a higher energy state by sunlight. The energy from the sunlight is converted to ATP and NADH, water is split releasing oxygen as a by-product and the ATP and NADH are used during the dark reaction to make C-C bonds4. During the light-dependent process, an important metabolic pathway occurs known as photophosphorylation occurs whereby energy is converted from a light-excited electron into the pyrophosphate bond of an ADP molecule4.…

    The controls for this experiment were having the same amount of water for each temperature (50mL), the same amount of bicarbonate infused in each spinach disk, the same sized spinach disks and the same light intensity on all of the beakers. By altering the temperature of water, the rate of photosynthesis was changed. Photosynthesis is less efficient at extreme temperatures due to the enzymes not properly functioning at these extremes. In the experiment, only the beaker filled with room temperature water (22°C) had the spinach disks’ rising to the top in 17 minutes, the rising to the top is a result of photosynthesis occurring and oxygen being produced. In comparison to the other two beakers filled with water of extreme temperatures (10°C and 60°C) which had little to no movement of the spinach disks and thus it can concluded no photosynthesis.…

    Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be controlled.…

    its color led to the formulation of this experiment. The experiment utilizes chloroplasts of spinach leaves to test the different color lights’ effects on photosynthesis. Green light is said to be the least effective at driving photosynthesis on the electromagnetic spectrum due to being mostly reflected and transmitted instead of being absorbed. Conversely, red light and white light is more effective at driving photosynthesis (Reece, 2011). Thus, a hypothesis was created stating that the rate of photosynthesis will be greater with a red light bulb compared to a green or white fluorescent light bulb.…

    Photosynthesis is a plant’s mechanism of converting sunlight and CO2 into energy in the form of organic material (Hohmann-Marriott and Blankenship 2011). Plant respiration is the process of using energy and oxygen to produce CO2 (Gonzalez-Meler et al. 2004). Almost all plants reproduce and respire, therefore it is important to know what factors could affect the rate of photosynthesis and respiration to better understand how plants function. Some research has shown that elevated CO2 concentrations may determine plant productivity by affecting plant physiological processes, and ecosystem structure and functions such as photosynthesis ( Xu et al. 1987).…

    Trees naturally sequester atmospheric carbon dioxide through photosynthesis and thus decrease global warming and its repercussions. Carbon dioxide is an essential component of the Calvin Cycle for the production of glucose, which is the primary energy source for plants as well as many herbivorous and carnivorous consumers. With the rapid increase in atmospheric carbon dioxide levels from anthropogenic activity since the Industrial Revolution, scientist suspect that carbon dioxide fertilization will amplify photosynthesis and, therefore, sequester more carbon dioxide from the atmosphere to the terrestrial carbon sink in the form of trees (Bonan 2008).2 Forests are a major terrestrial carbon sink and contain approximately 45% of terrestrial…
