Photosynthesis is a process in which plants must go through in order to survive. During the process of photosynthesis, plants have to use energy to make sugars as well as many other molecules from carbon dioxide and water as well. In this experiment we tested the effect turbidity would have on the process of photosynthesis, if any and how it would change the carbon dioxide intake. By making turbidity a factor in the photosynthesis process we figured that it could possibly affect the way photosynthesis is produced in plants. In order for photosynthesis to be as efficient as possible for plants, it needs to be able to get a decent amount of sun light in order for the plant to be healthy, and turbidity makes water murky which could have an effect on the photosynthesis process. In this experiment we found results that could possibly support the fact that turbidity, in the form of pollution or water runoff could manipulate the way plants photosynthesize.
Introduction
Turbidity is a measurement of how clear or unclear water can be (Michaud 1991). As total suspended solids increase in water the murkier it appears and also the higher it will tend measure it turbidity (1991). Many things can contribute to turbidity like storm water runoff, weather, industrial waste, and sewage (1991). Due to lack of light conditions, turbidity can also slow and even prevent a plant’s photosynthesis, which can cause a plant to die because of the reduced amount of dissolved oxygen and increased amount of acidity. Turbidity affects organism that are directly dependent on light, such as aquatic plants like elodea because it limits their ability to carry out photosynthesis successfully (1991). Turbidity also affects the organisms that primarily depend...

...n photosynthesis with one in a normal setting and the other with a piece of cloth that was imitating what it could possibly be like if there was high levels of turbidity in the water caused by things like industrial waste, water runoff, pollution, and sewage. We found that the beaker with cloth covered elodea was more acidic because we had to put more sodium hydroxide in it on order for it to be neutral. From it being more acidic supported our hypothesis on how turbidity would affect the process of photosynthesis. Since the water was more acidic, meant that more respiration occurred than photosynthesis because respiring plants causes’ water to become more acidic because respiration produces carbon dioxide and carbon dioxide mixes in the water creating carbonic acid and in this experiment the carbon dioxide came from someone blowing bubbles into the water (Walsh 33).
Investigating the Effect of Light Intensity on Photosynthesis in a Pondweed Aim: To investigate how the rate of photosynthesis changes at different light intensities, with a pondweed. Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis. The plant may stop photosynthesising when the pondweed is at the furthest distance from the lamp (8cm). Without light, the plant will stop the photosynthesising process, because, light is a limited factor. However once a particular light intensity is reached the rate of photosynthesis stays constant, even if the light intensity is the greatest.
Carbon dioxide is necessary for plants to carry out the process of photosynthesis, which is an important process because it allows plants to produce glucose, as well as oxygen. Based on evidence from previous experiments, the growth of the plant will reflect the amount of CO2 gas that is present in the environment (O’Leary and Knecht 1986). This means that the plant growth relies on the carbon dioxide in the atmosphere in order to be successful. Therefore, in several cases, it has been noted that when the concentration of CO2 is doubled, the plant growth will similarly increase (Carter et al. 1997). So, it can be concluded that by raising the amount of carbon dioxide in an environment, the surrounding plants will experience an increase in growth.
Experiment #1: The purpose of this experiment is to investigate the effects of baking soda and light intensity on the rate of photosynthesis of green spinach leave through the observation of floating disk.
The greater overall rate of absorbance change in all chloroplast samples (Figure 1) confirms role of chloroplasts’ in photosynthesis. However, the use of the supernatant sample as a negative control was expected to yield no activity, which was shown to be untrue (Figure 1) and is contributed to the contamination of the supernatant sample with chloroplast. The fragile envelope of the chloroplasts can be eas...
The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place
An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. In the results the pattern is that when the light intensity is higher the readings are generally higher. On the graph the less the light intensity the lower the gradient of the curve. the equation for the photosynthesis process is; CO2 + 2H2O + Light Energy = =
filters and count the number of oxygen bubbles given off using a pencil dot technique. Prediction I predict that with a blue filter the photosynthetic rate will be the as blue is a highly absorbent color it also has a short wavelength carries the most energy. The color to have the least photosynthetic rate will be green as it has quite a short wavelength so a lot of energy will be reflected by the plant and not absorbed in the sand. Yellow and orange will have average photosynthetic rates. although orange will be slightly more as it is more absorbent than yellow even low it has a longer wavelength and does not carry as much.
In this laboratory experiment, the rate of photosynthesis was measured through the use of the “floating leaf disk technique.” The leaf disks were placed into a syringe and the O2 and CO2 in the mesophyll layers of the leaves were removed and then replaced with sodium bicarbonate or water, causing the leaves to sink to the bottom of the container. If one determines the number of leaf disks rising to the top as a result of an increase in oxygen gas in the mesophyll cells, then the rate of photosynthesis is able to be measured because O2 is a product of photosynthesis. The first step of this experiment was a feasibility study of the variance in the photosynthetic activity of the leaf disks in both water and bicarbonate solutions. After five minutes of light exposure, all of the leaf disks in the bicarbonate solution (10 disks) had ...

The Effect of Light Intensity on Photosynthesis Of Elodea Canadensis Introduction I wanted to find out how much the light intensity affected the Photosynthesis in Elodea Camadensa. I decided to do this by measuring the amount of oxygen created during photosynthesis. Photosynthesis is the procedure all plants go through to make food. This process uses Carbon dioxide, water and light energy. It produces Oxygen and Glucose.
An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.
Significant amounts of energy which people can use. A way that we affect photosynthesis by our man made global warming which affects our atmosphere by adding more carbon dioxide to our air. An example of our man made global warming producers is the cars we ride on, cars release CO2 which gets release to our air. Another example how humans impact the process of photosynthesis is the cutting of trees which results in the lack of oxygen produced and carbon that can be
Photosynthesis is a key contributor to all living things; photosynthesis provides the oxygen, food, and nutrients that help all living things stay healthy and alive. Photosynthesis converts solar energy into the chemical energy of a carbohydrate. Photosynthetic organisms, including land plants, algae, and cyanobacteria, which are called autotroph...
