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 presence
Effect of Saltwater (NaCl) on the Production of CO2 in an Elodea Plant Julieta Medina-Rosas Marissa Aguilera, Jenine Hamed, Jessenia Torres Biology 1441 Sec 038; Professor Holmes; October 3, 2014 Elodea grows in freshwater and in this experiment the plant will be placed in a saltwater environment to test the efficiency or deficiency of photosynthesis and aerobic respiration. One of the plants was placed in a 75 mL diH2O solution while the other plant was placed in a 75 mL saltwater solution. There

Plants and other living organisms use the sunlight to produce oxygen (O2) and glucose (C6H12O6)
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)
three experiments, jan baptist van helmont willow tree , joseph priestley mint in jar , and lastly jan ingenhousz elodea and bubbles. they all show the findings of photosynthesis. Photosynthesis is the function in the plants on which they make food with. The plant also get energy from this process and they make oxygen for us to breath. The basic formula for photosynthesis is carbon dioxide, water then light to make sugar and oxygen. All plants are autotrophs which is a organism that
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 from sunlight
Photosynthesis Lab Report Abstract- The main purpose and objective of this lab is to determine if the consumption of carbon dioxide requires light or not during the process of photosynthesis. To complete this experiment the negative control is put under two different tests. Placing one test tube with no plant and exposed to light and the other test tube with the plant and no light exposure. Even though light is not required for the consumption of carbon dioxide, the hypothesis was not supported by
Mesocosm Design Lab (Practical #5) Anshul Krishnan : 11M Task: Design, set up, monitor and evaluate a sealed mesocosm, with a view to achieving a sustainable model. ———————————————————————————————————————— Defining The Problem: A Mesocosm is a designed natural environment which can be manipulated and can be controlled. The Main purpose of building a mesocosm is to be able to observe nature’s balance without human intervention; something that has been destroying our planet’s environment since
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
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 as an indication of the rate of photosynthesis. When the
