The Effect of Light Quality and Light Quantity on a Photosynthetic Plant

Figure one demonstrates that when light intensity increases, there is an increase in oxygen. This occurs due to lights effect on the photosystem II ability to transfer electrons and hydrogen ions from water to NADP+. An increase of light, increases the rate of water splitting within the chloroplasts, producing the O2 by-product. (Reece, et al, 2015) (Ping et al, 2015)

Have you ever really wondered how different variables can affect how plants go through photosynthesis? Well, in this experiment, the purpose was to see how various environmental conditions can affect the overall photosynthetic capacity of a specific plant. The factors, light, darkness, cold, and heat were applied to see how the different components would affect the photosynthesis on spinach plants. Each group was given a different factor to test. Out group was given the light factor. The hypothesis for this experiment is that when adding light as a factor, the light will affect the overall plant photosynthesis.

Duckweed is a small aquatic plant that is able to grow rapidly, making it the ideal specimen for our experiment. It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will lower the rate of growth in duckweed.

Introduction: Photosynthesis can be defined as a solar powered process that removes atmospheric carbon dioxide and transforms it into oxygen and carbohydrates (Harris-Haller 2014). Photosynthesis can be considered to be the most important biochemical process on Earth because it helps plants to grow its roots, leaves, and fruits, and plants serve as autotrophs which are crucial to the food chain on earth. Several factors determine the process of photosynthesis. Light is one these factors and is the main subject of this experiment. The intensity of light is a property of light that is important for photosynthesis to occur. Brighter light causes more light to touch the surface of the plant which increases the rate of photosynthesis (Speer 1997). This is why there is a tendency of higher rates of photosynthesis in climates with a lot of sunlight than areas that primarily do not get as much sunlight. Light wavelength is also a property of

The purpose of this lab is to observe the effect of white, green, and dark light on a photosynthetic plant using a volumeter and followed by the calculation of the net oxygen production using different wavelengths color of white and green light, and also the calculation of oxygen consumption under a dark environment, and finally the calculation of the gross oxygen production.

The purpose of this experiment was to investigate the effects of light intensity on the rate of photosynthesis in a Moneywort plant. By observing the plant in distilled water mixed with sodium bicarbonate, different light bulbs were targeted onto the plant. The measurement of the amount of bubbles present on the plant during the trial of the experiment enabled us to identify the comparisons between the activity of the light and the process of photosynthesis.

12. Describe two ways (two different things you could measure) to estimate the rate of photosynthesis in a particular plant. What specific measurements would you need to make for each in order to estimate GROSS photosynthesis?

The rate of photosynthesis is affected by environmental factors like light intensity, light wavelength, and temperature. This experiment will test the

An important part of photosynthesis is the intake of carbon; thus, it can be presumed that increasing the amount of available carbon will increase photosynthetic activity. In most plants there is an increased rate of photosynthetic rate, but it is limited by other factors and reaches a plateau (Lei H, Zhishan Z.

4.) What conclusions can you draw about which color in the visible spectrum causes the most plant growth?

photosynthesis happens in two stages: light reaction and carbon fixation also known as calvin cycle.light reaction TAKES PLACE IN THYLAKOID USE light energy to produces atp and nadph whereas, calvin cycle takes place instroma uses energy derived from light dependent reaction to make GA3P from CO2 ( Bio166 lab execise manual, 2015). the purpose of this experiment was to separate plant

However, the photosynthetic process can be affected by different environmental factors. In the following experiment, we tested the effects that the light intensity, light wavelength and pigment had on photosynthesis. The action spectrum of photosynthesis shows which wavelength of light is the most effective using only one line. The absorption spectrum plots how much light is absorbed at different wavelengths by one or more different pigment types. Organisms have different optimal functional ranges, so it is for our benefit to discover the conditions that this process works best. If the environmental conditions of light intensity, light wavelength and pigment type are changed, then the rate of photosynthesis will increase with average light intensity and under the wavelengths of white light which will correspond to the absorption spectrum of the pigments. The null hypothesis to this would be; if the environmental conditions light intensity, light wavelength and pigment type are changed, then the rate of photosynthesis will decrease with average light intensity and under the white light which will correspond to the absorption spectrum of the pigments.

Because chlorophyll-a takes in violet-blue, and orange-red lights to use in photosynthesis, it reflects green, and that is the color we see. This study investigates the relationship between the wavelength of light and the total respiration of the plant Elodea. The purpose is to see the effect of the presence or absence of certain wavelengths can have on the process of photosynthesis. Because Elodea is a plant that reflects green light, it can be assumed that red lights, the complimentary color to green will be absorbed the most contributing to the process of photosynthesis and respiration making the most oxygen.

     Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.

All this lights have equally conurbation towards plants growth but without any light then there is no process of photosynthesis which means there no plant growth at all. Photosynthesis is the procedure whereby radian vitality from the sun is changed over to the concoction bond vitality of glucose. In plants it happens in chloroplasts which concentrated cells. Chlorophyll atoms are instrumental in the first step, which is the change of light vitality to the substance bond vitality of ATP. Vitality to change carbon dioxide and hydrogen to glucose is then given by the ATP. Oxygen is discharged as a waste result of procedure. The reaction is shown below:
