Photosynthesis Experiment Paper

Introduction

Photosynthesis is the method through which leaves of olive vegetation and other plants tap sunrays to produce nutrients from the available carbon dioxide in the air and moisture (Abinandan & Shanthakumar, 2016). In green plants, photosynthesis usually involves a green pigment called chlorophyll the conversion of light energy by the plant in the presence of chlorophyll leading to the uptake of carbon dioxide by the plant hence releasing oxygen as a waste product (Lawson & Vialet-Chabrand, 2019). The oxygen released as a by-product used up by animals. In an attempt to establish photosynthesis, the team combined a variety of requirements such as sunlight, sodium bicarbonate, and water, among others necessary for the occurrence of the photosynthesis process.

Hypothesis for the Group

In the process of experimenting photography, the team had highlighted some lead hypothesis which would be used to confirm the results upon completion of the study (Abinandan & Shanthakumar, 2016). The primary hypothesis made by the team was that the application of the red color would accelerate the rate of photosynthesis by the green plant leaf. The assumption was made based on the fact that red color has the longest wavelength hence suitable for the speeding of the results. The blade was also exposed to light to provide suitable conditions for the process of photosynthesis (Lawson & Vialet-Chabrand, 2019).

Methods for the Group's Experiment

Upon collection of all the requirements, the sodium bicarbonate solution was made by adding forty (40) ml of distilled water to 0.5g of sodium. The available light was controlled often to find the exact aggregate speed of light effects for the experiment. A sizeable glass beaker that could fit the experiment materials was filled with fresh distilled water to be used during the test. Two desk lamps were placed on each side of the beaker. A plunger was then inserted into the syringe to facilitate filling of the needle with 8ml of sodium bicarbonate solution. The four leaves to be examined during the experiment were cut from the aucuba plant. Red coloring agents were added into the 40ml water in the beaker before putting in the leaves (Abinandan & Shanthakumar, 2016).

Results

There was no change in results of the leaf after 20 minutes of the experiment.

Analysis of the Results

The leaves were put under different lights to examine the rate of photosynthesis. The review was observed after five seconds, ten seconds, twelve seconds, fifteen seconds, and twenty seconds. Under white light and red light, photosynthesis process was recorded where the photosynthesis rate was high under the red light. Under the blue light, there was no significant change observed on the leaves (Abinandan & Shanthakumar, 2016).

The Function of Sodium Bicarbonate

Sodium bicarbonate (NaHCo3) is used during the experiment to provide carbon dioxide (Co2) for the leaves that lack carbon dioxide. CO2 is highly soluble in distilled water (Abinandan & Shanthakumar, 2016). The provision of carbon dioxide by sodium bicarbonate facilities the process of photosynthesis where there is less amount of carbon dioxide (Lawson & Vialet-Chabrand, 2019).

The Function of Different Backgrounds of Light

During the photosynthesis study, the leaves after being immersed in sodium bicarbonate they were placed under different light backgrounds. The diverse light background is used to analyze the effect of colored lights on the production of oxygen (Lawson & Vialet-Chabrand, 2019). The different colors produce different amounts of oxygen production when the leaves are put under each background. The rate of photosynthesis is affected by various factors, such as light intensity (Abinandan & Shanthakumar, 2016). The use of different lights can be used to examine the most suitable conditions for the plant that promotes photosynthesis process.

Failure of the Experiment

The photosynthesis experiment faced some hitches, which were contributed by different factors. The failure of the research was a result of inadequate lighting and amounts of carbon dioxide (Lawson & Vialet-Chabrand, 2019). The leaves were also not adequately punched hence leading to inaccurate results of the photosynthesis. The sodium bicarbonate used could have been ineffective for the photosynthesis experiment, thus facilitating its failure (Abinandan & Shanthakumar, 2016).

Conclusion

The conversation of sunlight energy into energy for the plant under the presence of chlorophyll by green plants has facilitated the balancing of the amounts of carbon dioxide and oxygen. The plants produce oxygen which is used by animals while consuming carbon dioxide. During the experiment, the leaves were placed under different white, red, and blue lights to investigate the influence of light on photosynthesis. The sodium bicarbonate was used to increase the amount of carbon dioxide where there were deficiencies. The failure of the experiment was the outcome of improper cutting of the leaves for the investigation by the team members. The sodium bicarbonate used for the research was also ineffective hence failed to deliver the amount of carbon dioxide used for the test.
