Abstract
Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place, the effect of chlorine in the presence of photosynthesis reactions were studied. Elodea was inserted into different beakers. One containing water and the other, bleach. The elodea was left unattended for an hour so that observations could be made to tell the difference in the results each beaker produced. After an hour the quantity of CO2 present was measured for the beaker with water and the beaker containing bleach. The results recorded were inconclusive because the bleach had a buffer that evidently lowered the pH, the beaker that had water in it showed signs that photosynthesis had transpired.

There are two important stages that take place during photosynthesis. There is a light independent reaction and a light-dependent reaction. The first is light-dependent. This occurs when there is natural sunlight. This is when a plant absorbs all the energy it can creating adenosine-triphosphate (ATP). The light-independent reaction is not tied to sunlight. This stage solely makes use of the ATP and Carbon dioxide (CO2) from the first reaction to create sugar. If there was no photosynthesis we wouldn’t be alive. Because it turns the power of the sun into chemical energy it is pertinent for all
