Observations about Data Table II and Graph II: Looking at Data Table II, it is representing the data presented in Graph II. Once the distance is calculated from light intensity (Data Table II). This implying that the rate of reaction is increasing as the source of light becomes more intense. A closer proximity is providing the plant with more energy and photons that will be converted into the production of glucose and oxygen. From point A to point B the graph is showing that when the light intensity increases so does a number of bubbles produced. This is because when the light becomes more intense, more light is hitting the photosystems involved in Stage I: Light-dependent reaction from photosynthesis. Exciting more electrons and ultimately…show more content…
The temperature of the experiment must remain consistent because when temperatures are low all of the enzymes that were involved in the catalysis converting CO2 to carbohydrates work slower and little to no photosynthesis is occurring. The opposite is true when the temperature is too high. The enzyme RUBISCO becomes decreasingly defective in fixing CO2 despite it not becoming denatured. So at too high or too low temperatures, there is little use of ATP and excited electrons restricting further photolysis. An improvement would be to use an acrylic and translucent sheet to act as a barrier between the experiment and the lamp. This will cause the light to hit the acrylic sheet first, absorbing initial heat, whilst still providing the plant with light. Another way is to make sure that the carbon dioxide concentration is also at a consistent temperature. It is suggested that the range temperature is 5˚C to 45˚C. So the experiment should use Co2 concentration at the temperature of…show more content…
caroliniana spreading problem, suggests that shading and blocking the amount of light exposed to the C. caroliniana plants may be able to be a control method for small populations. This is because this experiment has shown how significant light is in the process of photosynthesis. If the energy being transferred from the sun into the reaction is being interrupted the reaction with either slow down or not occur at all. Resulting in slower growth rates, and faster life cycles. Implying that if the light was taken away from the C. caroliniana plant, eventually the reactions would stop and kill them. The experiment’s findings support that at lower light levels photolysis is hardly occurring due to photons just barely striking the photosystems in chlorophyll. The resulted in fewer electrons in gaining energy and becoming excited. Thus meaning that fewer oxygen molecules are released because there are now fewer electrons needed to be replaced. As the intensity increases, the more photons are colliding with one another in the photosystems resulting in an increase of electrons to a higher energy level. These electrons produce NADPH. More photolysis reactions take place because their job is to replace electrons in the photosystems, leading to increased oxygen output. This will only continue until the reaction has approached its optimum level. There, the light intensity will no longer be the limiting
