Section 16.3 Photosynthetic Stages and Light-Absorbing ..
Our results show that different color lights definitely does have a strong direct correlation with the rate of photosynthesis/growth of a plant.
LIGHT ABSORPTION IN PHOTOSYNTHESIS
Absorption spectra showing how the different side chains in chlorophyll a and chlorophyll b result in slightly different absorptions of visible light.

In addition, since the team used different lights for the different colors, the light intensity may have been unequal, also resulting in inaccurate data.
If we were to do the lab again, we would include a trials with more colors of the visible light spectrum such as orange and violet to get a more comprehensive and seamless set of data.
In the interest of genetic engineering and agricultural applications, the authors analyze the relative importance of genes that control both metabolic and light reactions as well as the structure, arrangement, and orientation of photosynthesis.
Part of light spectrum used in photosynthesis - Science …
Visible light is a type of radiant energy within the electromagnetic spectrum; other types of electromagnetic radiation include UV, infrared, gamma, and radio rays. Photosynthesis is the process by which plants, some bacteria and protists, use the energy. In the electromagnetic spectrum, visible light is only a small part.

Oct 5, 2012. of green light is in photosynthesis. The electromagnetic spectrum Light. Visible light ranges from low blue to far-red light and is described as. However, visible light is just a small portion of the electromagnetic spectrum. Energy is inversely porportional to the wavelength – longer wavelengths have less. The visible spectrum is the only part of the electromagnetic spectrum that can be seen by the human eye. It includes electromagnetic radiation whose.

So how can these factors have an effect on the rate of photosynthesis? Lets start off with the light intensity. When the light intensity is poor, there is a shortage of ATP and NADPH, as these are products from the light dependent reactions. Without these products the light independent reactions can't occur as glycerate 3-phosphate cannot be reduced. Therefore a shortage of these products will limit the rate of photosynthesis. When the carbon dioxide concentration is low, the amount of glycerate 3-phosphate produced is limited as carbon dioxide is needed for its production and therefore the rate of photosynthesis is affected. Finally, many enzymes are involved during the process of photosynthesis. At low temperatures these enzymes work slower. At high temperatures the enzymes no longer work effectively. This affects the rate of the reactions in the Calvin cycle and therefore the rate of photosynthesis will be affected.

Green or yellow light will have the slowest rates of photosynthesis because they are reflected by the pigments in the plant.
DESCRIPTION & ANALYSIS
SOURCES OF ERROR AND IMPROVEMENTS
In this lab experiment, the team examines how the rate of photosynthesis is affected by different light colors in the leafs.
Photosynthesis title, definition and equation
A limiting factor is a factor that controls a process. Light intensity, temperature and carbon dioxide concentration are all factors which can control the rate of photosynthesis. Usually, only one of these factors will be the limiting factor in a plant at a certain time. This is the factor which is the furthest from its optimum level at a particular point in time. If we change the limiting factor the rate of photosynthesis will change but changes to the other factors will have no effect on the rate. If the levels of the limiting factor increase so that this factor is no longer the furthest from its optimum level, the limiting factor will change to the factor which is at that point in time, the furthest from its optimum level. For example, at night the limiting factor is likely to be the light intensity as this will be the furthest from its optimum level. During the day, the limiting factor is likely to switch to the temperature or the carbon dioxide concentration as the light intensity increases.
