Rate of Photosynthesis Experiment

Hypothesis is that Light is needed of for photosynthesis! My aim is to prove that light is needed for photosynthesis by destarching a plant and then placing it in the sun with one of the leafs being half cover with tinfoil so that the light doesn’t get to that area if the leaf. I will the test the leaf for starch using iodine solution and the areas that got expose to sunlight will have starch and will turn a dark blue or black colour. The area that had the tinfoil in on it will have no starch and…

Abstract Photosynthesis is directly affected by specific factors such as the level of carbon dioxide and the amount of light. In this study, we try to prove whether or not there is a significant statistical difference between the level of carbon dioxide and the rate of photosynthesis. To do this we investigated an aquatic plant, Elodea. A test was conducted to study the rate of photosynthesis which in this case was by observation of the number of gas bubbles produced when the plant was placed in…

Photosynthesis and Carbon Concentration Question: Does bicarbonate (CO2) concentration affect the rate of photolysis? Variable: The variable being investigated is bicarbonate concentration. Hypothesis: If one carbon dioxide source is removed, then the rate of photolysis will remain constant because carbon dioxide is not needed for photolysis. Materials: two 600 mL beakers 1.5 liters of water 1 dropper 4 drops of liquid laundry detergent 1 spoon 5 grams of baking soda (CO2 source) 1 stirrer 1 single-hole…

on rate of photosynthesis Research Question: How will the change in light intensity (by changing the distance between the light source and the plant) affect the amount of bubbles produced by a marimo moss ball? Background information: Photosynthesis is the process where green plants use sunlight to produce water and carbon dioxide as the food and generates oxygen as a product. 〖6CO〗_2+〖6H〗_2 O → C_6 H_12 O_6+〖6O〗_2 There are three main factors that can change the rate of photosynthesis. When…

Without carbon dioxide plants cannot photosynthesize. Through reading various books and web pages it was made clear that carbon dioxide is definitely one of the raw materials needed for photosynthesis, but I wanted to see whether this is actually true and if carbon dioxide is taken away completely will the plant photosynthesize at all? By taking a two plants of the exact same species, de-starching them both followed by putting plant one in conditions where carbon dioxide is taken away completely…

In conclusion to my investigation light is definitely needed and is important in the process of photosynthesis. Light is not only important in the light- dependant stage but the light-independent stage wouldn’t occur without light because light is changed from light energy to chemical potential energy and is carried out through the ATP and NADPH which takes the energy to the Calvin stage where that energy is used to make other organic compounds that we may be able to use like glucose. I also learned…

Effect of Air Pressure on the rate of Photosynthesis Problem/Question: Examine the effect of air pressure on the rate of photosynthesis in Basil (Ocimum basilicum) when contained in a growth chamber by means of measuring differences in Carbon Dioxide saturation of the surrounding air. Background: Basil is a relatively small plant commonly known for its use in the culinary arts as an herb. This plant was selected for this experiment as it is a prime candidate due to its wide availability. Possibly…

Title A study to investigate the effect of varying light intensities on the rate of photosynthesis and oxygen production. Introduction Photosynthesis is a multistep process where light energy is converted into chemical energy (G.Garab 1998). It takes place within the chloroplasts in the plants and involves two major steps; light dependent reactions and light independent reactions. Photosynthesis results in the release of oxygen and the removal of carbon dioxide from the atmosphere, which…

ABSTRACT This experiment demonstrates the effects of pH on the rate of photosynthesis by examining the behavior of leaf disks in different pH solutions under light. In this experiment, we used five different pH levels: pH 5, pH 6, pH 7, pH 8 and pH 9. These solutions were created using a combination of hydrochloric acid and sodium hydroxide. Spinancia olcerea or spinach, leaves were used in the experiment to examine the effects of pH on the rate of photosynthesis. The rate of photosynthesis was measured…

the water, then the rate of photosynthesis for Egeria densa will decrease because the lower the pH, the lower the oxygen content of the water and the lower the oxygen content the lower the rate of photosynthesis. As mentioned earlier, photosynthesis is the process in which organisms convert water and carbon dioxide into oxygen, and since it has been proven that the lower the pH the lower the oxygen content of the water, this leads me to believe that the rate of photosynthesis of the plants will decrease…
