Aim To observe the effect of light intensity on the rate of photosynthesis. Hypothesis Light intensity is directly proportional to the rate of photosynthesis. When the light isn’t intense, not many oxygen bubbles will be produced and thus observed. This indicates that the plant will not have enough derived energy from the sun to activate photosynthesis. Whereas, when the light intensity is great, the rate of photosynthesis will be high. Introduction Photosynthesis is the process of converting energy
Aim: To investigate the effects of different light intensities on photosynthesis in plants BACKGROUND INFORMATION: Aquatic plants can be used to demonstrate oxygen evolution in the process of photosynthesis. In theory, when an aquatic plant is placed in a solution containing a source of carbon dioxide (CO2), in the presence of light of appropriate intensity, the plant will photosynthesise and produce bubbles of oxygen-containing gas. These bubbles can be counted and the rate of bubbling can serve
Hypothesis: The rate of photosynthesis will be slow in extreme temperatures (either too hot or too cold). Hypothesis Explanation: The change in temperature levels during the process of photosynthesis will affect the amount of oxygen released. The rate of photosynthesis can be inferred by measuring the amount of oxygen released. Therefore if in extreme temperature like too hot or too cold the amount of oxygen released would be less and so therefore the rate of photosynthesis would be slow. Background
Photosynthesis Assignment Lance Misland Ms T Joshua Marine Biology 1 (MAB150S) 14 September 2015 Introduction: Photosynthesis is the process that primary producers undergo in order to make food for them; they do this by converting light energy into chemical energy, storing it in bonds of sugar. This process occurs in organisms that have chloroplast (plants and some algae), using chlorophyll to capture the light. However, plants only need light energy, CO2 and H2O to make sugar (Biology, 2014)
The Effects of Light on the Rate of Photosynthesis Tong Wu October 10, 2014 Lab section 82036: Mondays at 12:00 PM - 2:45 PM Performed and written by: Nayobe Bivins Stephanie Wigmore Abstract The objective of this experiment was to determine the relationship between light and the rate of the photosynthesis of the Elodea plant; that is, to describe the effects of a light source on photosynthesis. To test the effects of light on photosynthesis in this experiment, the Elodea plant was placed under
The metabolism simulation lab allowed groups to use a computer simulation to look at aerobic respiration and photosynthesis. Each group used either Microsoft paint, word, or excel to create charts and graphs to represent the metabolism simulation lab. Additionally, it allowed groups to look at the light intensity and quality in adenosine triphosphate. Our group created three tables on Microsoft excel. Of the three tables, the first table represented the ATP production in aerobic conditions related
PLANNING LAB 3 Research Question: How does light intensity affect the rate of photosynthesis of green spinach leaves? Background: Spinach leaf disc normally float but the spinach discs will be filled with fluid by using a syringe (explained in method), once they are filled it affects the buoyancy of the spinach disc causing them to sink. Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen. When photosynthesis occurs in the leaf disc oxygen will be released
Effects of Light Intensity, Light Wavelength, and the Activity of Pigments on the Rate of Photosynthesis By Rachel Whaley 3/23/15 Yumna Zahid Biology 111, Section 537 Abstract Photosynthesis converts carbon dioxide, water, and light energy into chemical energy (glucose) and oxygen, and serves as the foundation for most food webs. The distance chloroplasts were from a light source was varied and a spectrophotometer measured the rate of photosynthesis in the first experiment. Light intensity and
ammonia, light intensity, and light color on the Hill Reaction in isolated chloroplasts. Chloroplasts were separated from spinach using the centrifugation technique. The chloroplasts were mixed with different proportions of ammonia and DCMU to distinguish between uncouplers and inhibitors to the electron transport in photosynthesis. The second experiment tested for the effects of light intensity and color. Different distances and colored film were used to measure the reaction rate of photosynthesis in
Discussion: The rate of photosynthesis is dependent on the light intensity and the chloroplasts. Spinach was blended and used in this lab for the chloroplasts. Cuvette one solution was clear with a tint of green, it included phosphate buffer, distilled water, and unboiled chloroplasts. The green colour in the solution was the chloroplasts. No DPIP was added to the solution so therefore the colour did not change. Each time after 6, 13, and 20 minutes in light, the transmittance was adjusted on the
