How can you look at a landscape and tell whether a lot of photosynthesis usually happens there? The chemical equation for this process is shown below. How does the level of light affect the rate of photosynthesis?
Fair Testing The fair testing will be carefully checked so the results do not come out to be void. Elodea water plantlight source 40 Watt bulb and sockettest tube or long slider empty bottledistilled water, tape, baking soda, a clear plastic funnel, thin piece of wood, metric ruler, and long stick matches.
Chloroplasts act as a energy transducers, converting light energy into chemical energy. Figure 1 After enough gas has been produced and collected, the test tube will be removed, and inverted, and a glowing piece of wood is inserted into the tube.
So water is an important limit on a plant. Light is an extremely important factor for the process. If you look at a spectrum from nmnm.
When you increase the level of light, plants will photosynthesize more. Light intensity is usually defined as the energy hitting an area over some time period. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.
This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant. I am not sure what you mean by "level" of light, but I will answer your question in to ways - in terms of the intensity of light and wavelength of light.
The outcome variable which will change as a result of this experiment will be the amount of oxygen made in the experiment due to the amount of light intensity increases causing the plant to photosynthesise more. Thanks for asking, Answer 2: Photosynthesis is the building up of sugar molecules using carbon dioxide and water as the raw materials.
So in our case the variable light energy light intensity will be used.
When this occurs, leaves can experience sunburn damage. The fact that no gas was produced while the setup was kept in the dark showed that light was the cause of the production of oxygen.
The project investigator will place a sprig of elodea underwater plant under a clear funnel then fill a test tube with water and it placed on top of the funnel. While exposed, the plants will produce a gas which is collected in an inverted test tube.
From the observations and tests made a data table will be generated and results displayed in the form of a graph. This mean it will absorb any wavelength of light which is not in the green spectrum of light.
Most of the time, when the intensity of light is high, you will get a a greater rate of photosynthesis. Actually, most places on Earth have the same amount of carbon dioxide in the atmosphere, but a plant can only get it by opening holes in its leaves.
When we think of photosynthesis as a process, we can see that there are at least three things that can limit the process: The elodea underwater plants can be purchased from a pet supply store, and a test tube can be borrowed from a high school science teacher or found in a toy chemistry set.
In deserts, plants use hairs or scales on their leaves to reduce the amount of light they receive to keep the light from driving the temperature up too high or causing the plants to dry out.
We will be doing each light intensity test three times to get an average for our graphs. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy.
Also if they decrease then it will be likely that the rate of photosynthesis will decrease as well. The research aspect of this science fair project is to assess how light intensity affects the rate at which photosynthesis occurs and the rate of oxygen production. So by level of light you probably mean light intensity which is something that can be measured.
Photosynthesis needs light, but it also needs other things, and too much light can create heat and dryness that are bad for photosynthesis.Biology Coursework ÐŽV Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on 4/4(1).
The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place - The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place Hypothesis: I predict that as the intensity of light is increased, so would the photosynthesis.
The number of light photons hitting the chlorophyll pigments increase as the light intensity rises. This in turn increases the rate of photosynthesis.
The whole process is so effective that in optimum conditions 90 percent of light is absorbed. The Effect of Light Intensity and Temperature on the Rate of Photosynthesis - The Effect of Light Intensity and Temperature on the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant.
An increase in light intensity will increase the rate of photosynthesis. if the light is low then the rate of photosynthesis will also be slow. According to Molina. D and Alegrors () without enough light a plant cannot photosynthesise very quickly even if there is plenty of water and carbon dioxide.
Platform for the analysis of photosynthesis The Grossman Lab has identified many mutants in Chlamydomonas defective in photosynthetic function. A streamlined platform is being developed to analyze these mutants which involves spectroscopy, fluorometry, CO2 fixation and oxygen evolution.Download
