Carbon Dioxide Experiment in Photosynthesis - 1311 Words
Without carbon dioxide plants cannot photosynthesize. Through reading various books and web pages it was made clear that carbon dioxide is definitely one of the raw materials needed for photosynthesis, but I wanted to see whether this is actually true and if carbon dioxide is taken away completely will the plant photosynthesize at all? By taking a two plants of the exact same species, de-starching them both followed by putting plant one in conditions where carbon dioxide is taken away completely, and plant two will then be put in conditions where carbon dioxide is added, after a day or two in these conditions leaves from both plants will be tested for starch, if the leaf tests positive for starch it means that the plant hasâ⬠¦show more contentâ⬠¦All sources ultimately made it clear that carbon dioxide is very necessary for photosynthesis as well as the amount of carbon dioxide affecting the rate at which a plant can photosynthesize. Methodology and presentation of findings Method: â⬠¢ Step 1: get two well watered pot plants of the same species and put them in a dark place for about 48 hours so that they use up their starch. â⬠¢ Step 2: do the starch test (see from step 6-11) to make sure there is no starch present. â⬠¢ Step 3: put each plant under a bell jar and on top of a glass plate where you put Vaseline around to prevent any outside air from coming in and any inside air from escaping out. â⬠¢ Step 4: In bell jar #1 put sodium bicarbonate solution in a small beaker to release carbon dioxide into the jar. â⬠¢ Step 5: In bell jar #2 put sodium hydroxide solution in a small beaker to absorb any carbon dioxide that may be present inside the jar. â⬠¢ Step 6: leave both jars in a warm sunny place for about 48 hours and then test a leaf from each plant for starch. â⬠¢ Step 7: put each leaf in a beaker of boiling water to soften them. â⬠¢ Step 8: put each leaf into a test tube with ethanol and then put that test tube in a beaker of boiling water to bring the ethanol to a boil; this is to extract any green colour from the leaf. â⬠¢ Step 9: take each leaf out withShow MoreRelatedThe Influence of Light on Photosynthesis1500 Words à |à 6 Pagesinfluence of light on Photosynthesis Table of contents Front page and table of contents Page 1 Introduction Page 2 Review of literature Page 3 and 4 Methodology and presentation of findings Page 5 and 6 Procession of findings Page 7 Conclusion Page 8 Introduction In this project I believe the outcome will be that light energy is essential for photosynthesis to occur. The aim was to show that light is necessary for photosynthesis.

(2016) Biology How Life Works. New York, NY.). It is a system that uses plants and specific algae to synthesize molecules from both water and carbon dioxide. The oxygen we breathe and the food we eat is fueled by photosynthesis because it is anRead MoreCarbon Dioxide And The Rate Of Photosynthesis1315 Words à |à 6 PagesAbstract Photosynthesis is directly affected by specific factors such as the level of carbon dioxide and the amount of light. In this study, we try to prove whether or not there is a significant statistical difference between the level of carbon dioxide and the rate of photosynthesis. To do this we investigated an aquatic plant, Elodea. A test was conducted to study the rate of photosynthesis which in this case was by observation of the number of gas bubbles produced when the plant was placed inRead MoreThe Effect Of Photosynthesis On The Rate Of Photosynthesis1660 Words à |à 7 PagesAbstract: During photosynthesis plants take light energy and turn it into chemical energy. The purpose of the study was to test the effect of various lighting conditions on the rate of photosynthesis. In this experiment the rate of photosynthesis is measured by timing how long it takes photosynthesis to occur in ten leaf disks that are in a solution of carbon dioxide. The prediction for this experiment was t hat if a plant receives more light, then it will have a higher rate of photosynthesis. The data supportsRead MorePhotosynthesis And Cellular Respiration. Photosynthesis1032 Words à |à 5 PagesPhotosynthesis and Cellular Respiration Photosynthesis and respiration are reactions that complement each other in the environment. In reality, they are the same reactions, but they occur in reverse. During photosynthesis, carbon dioxide and water yield glucose and oxygen. Through the respiration process, glucose and oxygen yield carbon dioxide and water. They work well because living organisms supply plants with carbon dioxide, which undergoes photosynthesis and produces glucose, and these plantsRead MoreThe Relevance Of Photosynthesis And Nature1545 Words à |à 7 Pages The Relevance Of Photosynthesis To Nature The natural light that shines onto the Earth is said to be the driving force behind all life. Itââ¬â¢s fascinating to find out that the green matter around us that we tend to take for granted is mankindââ¬â¢s source of energy - which is a necessity for every living being even in its lowest form. We can literally define photosynthesis as ââ¬Ësynthesis with the help of lightââ¬â¢. It is also defined as the basic process of life whereby plants absorb energy from sunlightRead MorePhotosynthesis Is The Conversion Of Light Energy Essay1371 Words à |à 6 PagesPhotosynthesis is the conversion of light energy to chemical energy. There are many different factors that can affect the rate of photosynthesis, those being light intensity, the temperature of the water, the amount of carbon dioxide in the water, and the color of the light. In this experiment we chose to alter the color of light that was used in the process involving the aquatic plant Elodea while maintaining the other 3 factors. This experiment was conducted to see how much of an effect the colorRead MoreLight Is A Form Of Energy That Travels Through Electromagnetic Waves1252 Words à |à 6 Pagescan either be absorbed, reflected, or refracted. Light is necessary in photosynthesis as it absorbed by the chloroplast and it excites electrons of the atoms in the thylakoid. The excited electrons then release energy when they go back to ground state in the electron transport chain where the energy is used to change ADP into ATP and perform photolysis which products are needed to create glucose in the Calvin cycle. Photosynthesis is important to life on earth because one product of the reaction isRead MoreThe Importance of Light During the Photosynthesis Process1713 Words à |à 7 PagesPhotosynthesis is a chemical process by which green plants use the radiant energy to synthesize certain nutrients using water and carbon dioxide. This process to happen efficiently it requires the presence of light, wa ter carbon dioxide, chlorophyll and enzymes. During the process of photosynthesis, carbon dioxide plus water in the presence of sunlight, enzymes and chlorophyll produce glucose and oxygen as waste product. The radiant energy is broken down the water into hydrogen atom and oxygen atomsRead MoreHow Photosynthesis Is A Redox Response1277 Words à |à 6 PagesPhotosynthesis is a redox response, which obliges carbon dioxide, water and light to deliver water and a 6-carbon sugar. Amid this response H2O is oxidized and CO2 is lessened. The methodology of photosynthesis comprises of 2 sections; a light response and a light-free response. The strategy for changing light vitality into concoction vitality for the development of NADPH and ATP is done through the light responses. Light autonomous responses use carbon dioxide and the results of light responses
