The 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

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

Photosynthesis is a process done in the chloroplasts of plant cells that is beneficial to all of life. Plants are able to convert light to energy which is beneficial to the plants‚ while also giving off oxygen as a byproduct for humans. Chloroplasts are in the thylakoid discs of a plant cell‚ that contain chlorophyll a and chlorophyll b‚ which are it’s light-capturing pigments. Colors in the wavelengths are either absorbed or reflected by the chlorophyll in which case green is reflected and colors

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

Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However‚ after reaching an intensity of 10‚000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may‚ in fact‚ slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100‚000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed

“Investigate how light and darkness contribute to the cycling of carbon through both cellular respiration and photosynthesis of a plant” we devised a hypothesis that states‚ If we place the two test tube‚ one with carbonated water and the other regular water‚ with the Elodea inside a dark environment it will perform cellular respiration as it will not receive enough light energy to perform photosynthesis. From the result of our experiment we found that the test tube with tap water and Elodea changed from

Factors Limiting Photosynthesis The rate of photosynthesis increases with increasing light intensity. But too much light intensity can slow down the rate of photosynthesis because the light damages chloroplasts in the leaf. The higher the temperature the greater the rate of photosynthesis as photosynthesis is a chemical reaction and chemical reactions increase with temperature. But at temperatures above 40 C the rate slows down because the enzymes involved are destroyed
