Sativus Abstract: Light from the Sun is a full spectrum of different wavelengths of light. Scientists refer to this light as “white light”. When the wavelength of visible light changes‚ so does the color seen by the eye. The shortest wavelengths visible to the human eye are violet (400 nanometers). The longest wavelengths visible the human eye are red (700 nanometers). Each plant is affected differently by the changing wavelengths of light. The purpose of this experiment is to test the effects

effect of different wavelengths of light on photosynthesis rate in spinach leaves Abstract: This experiment was performed to test the effect of different wavelengths of light had on photosynthesis. According to the results gathered we can say that if two plants are put under different lights‚ one green and one a normal light‚ that the plant under the normal light will perform photosynthesis at a higher rate than the plant under the green light. This experiment is important because it shows us

The purpose of the experiment is to determine the effects of sugar on photosynthesis in Elodea. Sugar water with Elodea‚ water with Elodea‚ and water (control) are used to test for photosynthesis. Five drops of sugar water were added to sugar water with Elodea beaker. The three beakers were left under normal light for photosynthesis to occur. After 60 minutes‚ NaOH solution was added to each beaker to test the volume of CO2. The result shows that both Sugar water with Elodea and water with Elodea

Rate of Reaction Experiment Introduction : in this term in chemistry class I was learning about rate of reaction. As defined by the Britannica encyclopedia‚ a chemical reaction is a process where one or more substances (reactants) are converted to one or more different products because of the rearrangement of atoms of the reactants. For the reaction to occur‚ the particles must collide with each other and in order to succeed there must be enough energy for the collision because a collision with little

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate of photosynthesis

Photosynthesis Matt Lazar 5/13/96 8th Hr. When you and me eat‚ we find our food. When plants eat‚ they make their own food and energy. They make their food and energy through a process called photosynthesis. Through photosynthesis oxygen is also produced. Photosynthesis is "a process in which green plants synthesize carbohydrates from carbon dioxide and water....The reverse of this reaction provides energy for plants‚ for animals that eat plants‚ for animals that eat animals that eat plants"

Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If there

of wavelength of light on the rate of photosynthesis was investigated in this experiment. The results from Figure 13 suggest that white light‚ containing all wavelengths of coloured light‚ has the highest rate of photosynthesis. Purple light had the second highest efficiency‚ followed by blue‚ red‚ and yellow light. Green light was significantly less efficient‚ producing the second lowest pH reading (Figure 14). The samples exposed to no light had the lowest rate of photosynthesis. The hypothesis
