Photosynthesis is a process by which green plants and other organisms transform light energy intochemical energy. During the photosynthesis, light energy is captured and is used to convert water, carbondioxide, and minerals into oxygen and energy-rich organic compounds (Lambers, 2020).Sunlight allows the plant to perform photosynthesis, a process that is required for plant growth andmaintain its health. Photosynthesis allows plants to synthesize glucose from carbon dioxide and water torelease oxygen. Moreover, the sun naturally provides the plant with the right balance of blue and red rayswhich are needed for the plant to survive.Should there be an instance that the plant would have nosunlight, the plant will grow upward, looking for sunlight. This survival mechanism of plants thatmaximizes their chance of getting light is known as etiolation (Shankel, 2017).Plants extract carbon dioxide, a byproduct of the respiration of humans, from the air and use it in thephotosynthesis process. Carbon dioxide with water allows the plant to extract what it needs for food.Photosynthesis separates carbon dioxide and water into their molecules and combines them into newproducts such as oxygen and C6H12O6, a substance similar to glucose that feeds the plant. (Turtenwald,2018).In the photosynthesis experiment, there were two solutions with two different setups. The firstsolution is the baking soda with detergent set up in an area with artificial light and in an area without anysource of light. Baking soda has a chemical formula of sodium bicarbonate (NaHCO3). An anion thatserves as the carbon source for photosynthesis is the bicarbonate ion. As photosynthesis proceeds, oxygenis released into the interior of the leaf that changes the buoyancy of the leaf, and causing the discs to rise(Helmenstine, 2019).The disc leaves in the baking soda solution at the area where there is light, all the disc leaves floatedin less than 10 minutes. When the disc leaves were exposed to the artificial light, the discs used thepresence of the light to use carbon dioxide present in baking soda and water to produce oxygen andglucose, making the leaves rise. When the disc leaves were exposed in a dark place, there was no sourceof light, therefore, the process of photosynthesis could not proceed.The disc leaves in the detergent solution in both places of light and dark did not rise since havingdetergent solution alone decreases the surface tension of the water. Surfactants are compounds that lowerthe water’s surface tension which works by separating water molecules from one another. Surface tensionis the property of the liquid surface that allows it to resist an external force, due to the cohesive nature ofits molecules (Lotha & Bhuta, 2017).Fig. 12.
