INTRODUCTION
The sun plays a vital role in sustaining an entire living world whether indirectly or directy using a transformation process called photosynthesis. This process assists in nourishing plants and keeping them alive. For example, trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason, in order to survive the chloroplast in plants must capture light energy from the sun and convert it into chemical energy that is stored in sugar and other organic molecules (Photosynthesis, 2014, p. 185). In plants that contain chlorophyll, the photosynthesis process splits H20, releasing oxygen, and storing the produced energy resulting from the chemical reaction inside a carbohydrate molecule. This is shown in the following equation for photosynthesis: Water + Carbon Dioxide (with the aid of chlorophyll and light energy) Glucose + Oxygen (Matthews & Lindbeck, 2013).
In addition, the rate of photosynthesis has varying factors, which among them include the amount of carbon dioxide present, the light intensity, and the type of organism. In this experiment, our aim was to investigate how the amount of light intensity affects …show more content…
As shown in the data collected in the graphs from the experiment, the distance between the lamp and the Elodea plant played an essential role in the rate of respiration. In an intact plant, the rate of O2 production was 6.994 when exposed to high levels of light at a distance of 25cm. However, when the plant was exposed to high levels of light at a distance of 75cm the rate of O2 production was 3.5188. This is partly because at 25cm the lamp exposes the chlorophyll in the plant to more light, which it is able to
