The rate of photosynthesis may vary with changes that occur in environmental temperature, wavelength of light, and light intensity. Using a photosynthetic organism of your choice, choose only ONE of the three variables (temperature, wavelength of light, or light intensity) and for this variable. • Design a scientific experiment to determine the effect of the variable on the rate of photosynthesis for the organism • Explain how you would measure the rate of photosynthesis in your experiment
the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. To do this, I will place a piece of pondweed in varying light intensities and temperatures, and observe the amount of oxygen being given off. I am using pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water. Introduction Photosynthesis occurs
Introduction: Photosynthesis is a process that plants use to create glucose by utilizing sunlight, carbon dioxide, and water. The pigments in a plant absorb light by way of photosynthesis and each pigment can absorb different colors but will reflect green light because it does not really absorb it. Therefore, plants always appear to have a green color. Plants have four pigments that were tested in this exercise called carotenoids such as carotenes/xanthophyll, also pigments chlorophyll a and chlorophyll
a wide variety of environments, but how does the environment affect photosynthesis rate? Temperature, light intensity, water supply, and the amount of carbon dioxide are all factors that contribute photosynthesis rate. For the lab on photosynthesis, our group tested the Anacharis Bunch plant, which is an aquatic plant that needs moderate light in order for photosynthesis to occur (“Anacharis (Egeria densa)”). For photosynthesis to take place, energy from the sun is required. When sunlight strikes
Abstract: 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 that if a plant receives more light, then it will have a higher rate of photosynthesis. The data supports
the rate of photosynthesis using leaf discs. Aim : To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Introduction : The simple concept of photosynthesis is that it can occurs in the presence of light, which takes place in the chloroplasts of green plant cells. Photosynthesis can also be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. The chemical equation for photosynthesis can
Abstract 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 in
Photosynthesis is a process used by plants and other living organisms that use light energy from the sun into chemical energy that can later be used as energy for other organisms. Numerous factors that influence the rate of which photosynthesis occurs, which includes temperature, amount of light and carbon dioxide. The aim of the experiment was to investigate the effect of increasing concentration of carbon dioxide on the rate of photosynthesis. For example, to test the hypothesis, the effect of
The Effect of Environmental Conditions on the Rate of Photosynthesis 2. Introduction Background Photosynthesis is the conversion of light energy to chemical energy into sugars. It is the process in plants that uses carbon dioxide, water, and sunlight from its surroundings and releases oxygen as a byproduct (6H2O+6CO2+light energy -> C6H12O6+6O2). Photosynthesis is required for plants because they are autotrophs, organisms that make their own food. Plants require a specific environment that is ideal
Photosynthesis 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 plants
