    However, too much carbonate might slow down the rate of photosynthesis within the disks. This is because the addition of too much carbonate will directly increase the amount of carbon dioxide in water thus increasing the pH. When the pH is increased, the enzymes in the ivy leaf discs will denature, thus no longer allowing them to function. Method and Materials: Variables: Independent: This was the different concentrations of sodium bicarbonate solution (1%, 2%, 4%, 6%, 8%, and 10%). This

    placed in a sugar molecule. This pathway is called C-3 photosynthesis. This is the way that most broadleaf plants make sugars during the dark reaction. C-3 photosynthesis has a disadvantage though. Oxygen competes with CO 2 for a binding site during the dark reaction. Sometimes sugars are not formed, but energy is still expended to complete the cycle. This is called photorespiration. Another dark reaction pathway is called C-4 photosynthesis because 4 carbons are fixed or placed in a sugar molecule

    chloroplasts and the rate of color loss was monitored by a spectrophotomer to measure the transmittance of light1. To begin the experiment, the spectrophotometer was set to a wavelength of 605nm, which is the wavelength for photosynthesis. In order to measure photosynthesis, we used a suspension of chloroplasts obtained from spinach leaves. As a control for the effect of temperature, one of the samples was kept at room temperature which is 25° C. We began our experiment by creating 4 sample

Materials and Methods Before beginning our experiment, some spinach leaves were taken from the refrigerator, removed from their stems as the stems do not photosynthesize, and set under a light for 20 minutes to “restart” photosynthesis. To protect the chloroplasts in the spinach, the leaves were placed in an isotonic 0.5 M sugar solution. An isotonic solution was necessary so the plant’s cells would not burst. The sugar and

  • How Light Intensity Affect Photosynthesis Essay example

    DiscussionLight intensity affects photosynthesis. This is because from table 1 the results show that an increase in light intensity will increase the rate of photosynthesis. Simply light and carbon dioxide are used to investigate the rate at which photosynthesis is occurring. As the light is moved away from the plant the number of oxygen tend to increase. An increase in light intensity will increase the rate of photosynthesis. if the light is low then the rate of photosynthesis will also be slow. According

    Effects of light. Light initiates the opening of the stomata, which results in carbon dioxide being absorbed for photosynthesis during the light-dependant phase, during this the rate of photosynthesis will increase. Brighter light means an increase in photosynthesis At low light intensities, as light intensity increases, the rate of the light-dependent reaction, and therefore photosynthesis generally, increases.

Evaluation: Our experiment went fairly well, however our results were not very accurate for various reasons. Firstly, the lamp we sued was a simple table lamp instead of UV light used to mimic sunlight. Therefore the light used was not an accurate imitation of sunlight. This may not have allowed the plant to increase it’s rate of photosynthesis to the fullest. Therefore the

    I also predict that the rate of photosynthesis will increase in direct proportion to the increasing light intensity up till a certain point where the rate will decrease and level out. The proportional increase will happen because of the reason that I have already mentioned above, and there will be a point where the light intensity will not affect the rate of photosynthesis because another factor will be limiting the rate of photosynthesis e.g. level of carbon dioxide or temperature

    After 9 minutes (“more time under light source”), there were more bubbles than at the beginning. However, it was not due to the closeness of the lamp but to the amount of time under it.

Temperature, if the temperature is too the rate of photosynthesis will decrease and as the temperature increase the rate of photosynthesis will increase as well. But if the temperature gets too hot the enzymes begin to lose their shape (denature) thus they are unable to function properly and the rate of photosynthesis decreases again. pH, the pH level effects the enzymes in the plant cells because if the pH level of the enzymes
