how does light color affect the rate of photosynthesis

Light is made up of three different colors: red, blue and green. The percentage of light absorbed by plants in photosynthesis differs for the colour of the light. Our academic experts are ready and waiting to assist with any writing project you may have. The range of electromagnetic radiation is known as the emission spectrum, a small strip of which is visible light. Violet light was also unusually low suggesting inaccuracy and error. To improve on this I will perform the experiment in a darkened room on my own. If there is enough water, carbon dioxide, and the temperature is right, light becomes the factor which will affect photosynthesis. Understanding Trustees' Duties and Responsibilities in Managing a Trust, Estate Planning 101: How to Probate a Will, The Differences Between “Defamation,” “Libel” and “Slander”. Data collection and Processing (Quantitative and Qualitative data): Measures and average number of bubbles produced. Any scientific information contained within this essay should not be treated as fact, this content is to be used for educational purposes only and may contain factual inaccuracies or be out of date. It is safe to assume that green would have to lowest rate of photosynthesis because it is reflected by the leaves of plants and red/violet would have the highest rate of photosynthesis. To what extent does the colour of light have on the rate of photosynthesis on Cabomba Aquatica plants? Photosynthesis needs water, carbon dioxide, chlorophyll, light, and the right temperature. If the algae grow under the green LED light and in complete darkness, then they will produce less oxygen and cells than under the white LED light, due to the inefficiency of photosynthesis. This diagram would indicate that pure yellow would be pretty ineffective for any pigment. The error bars where slightly large for some of the wavelengths of light indicating inaccuracy of results. Yes, the color of light affect the growth of the mongo and any other green plant. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. ... How Does The Intensity And Distance Of A Light Source Affect Rate Photosynthesis Quora ... Bill Nye Light And Color Worksheet Quizlet. Red and violet visible radiation are on opposite terminals on the seeable light spectrum. Free resources to assist you with your university studies! The process by which they do this is called photosynthesis. Plants grow best when exposed to the entire visible light spectrum. Different plants may photosynthesise at different rates and different sized samples may also affect the rate of photosynthesis. This issue is a minor one yet it still adds to the unreliability and inaccuracy of my results. Essentially, the reason why plants are green is they are absorbing the other wavelengths of light but reflecting back the green. The hypothesis was that the lights higher on the light spectrum, like blue, would have the fastest rate of photosynthesis because the energy is the highest; the green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it … We're here to answer any questions you have about our services. Red visible radiation has the longest wavelength of 700nm whereas violet visible radiation has the shorter wavelength of 400nm. The rate of photosynthesis is affected by the different wavelengths of light a plant is exposed to because different pigments in chloroplasts … Biology, The effect of Light Colour on the Rate of Photosynthesis. While plants take in all colors and wavelengths of light, some colors affect the plant species more than others (Sanchez, 2014). Each pigment absorbs certain colors of light more efficiently than others do. Red and violet visible radiation are on opposite terminals on the seeable light spectrum. Light is an extremely important factor for the process. Perhaps the yellow filter was in fact a mix of multiple wavelengths causing the strange results I gathered whilst white light was a mix of all wavelengths. THE EFFECT OF DIFFERENT LIGHT COLORS ON THE PHOTOSYNTHETIC RATE IN PLANTS By: Emily, David, Michael 10/20/2014 Mr. Minnich AP Biology ABSTRACT In this lab experiment, the team examines how the rate of photosynthesis is affected by different light colors in … Looking for a flexible role? By growing the plants beneath color filters, you can determine which color of light produces optimal growth. The level of uncertainty for time was ±1 second. Therefore, different light colors have an effect on photosynthesis and respiration rates. Looking at the image above which shows the literary value of wavelength and rate of photosynthesis it became evident to me that repeated investigations are important. Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, pH and intensity of light. Light is in the form of electromagnetic energy that travels in wave form. Firstly I performed my experiment at the same time as the rest of the students within the class meaning that the light intensity was mixed with those near to mine thus increasing the light intensity and affecting my results. They are favoured by aquarists as oxygenating plants for fishtanks. The color of light affects the rate of photosynthesis when the production of oxygen increases at 450 nm (blue), drops, then rises again at 660 nm (orange). Plants absorb both red and purple light waves, however because purple wavelengths are shorter, they contain more energy. I performed my experiment at the same time as the rest of the students within the class meaning that the light intensity was mixed with those near to mine, The increase in light intensity may have been minute yet it still could have affected my results and the accuracy. Oxygen production is high for orange and blue light, and low with purple, green, and red light. Scientists experimenting with different colours of light agree that exposing plants to limited light spectra alters the process of photosynthesis. Yellow light should have also been one of the lowest rates however in my experiment I found it to be one of the highest and blue light showed to have one of the lowest rates. This investigation will be focusing on which wavelengths of visible light, colour of light, has the highest rate of photosynthesis. Plug in the 100W light bulb in and turn it on to its side so that it is facing the beaker. These wavelengths correspond to light that appears violet-blue and red to the human eye. Light absorption by chlorophyll a and thus, the efficiency of photosynthesis, peak at about 450 nanometers and 650 nanometers. The leaves of a plant are green because the chlorophyll within them absorb all other wavelengths of light and reflects green light.
