The process of photosynthesis is when plants use the energy in sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates. Photosynthesis occurs inside a cell organelle called the chloroplast. The chloroplast contains green pigments called chlorophyll, which capture the energy in sunlight. The equation for photosynthesis is as follows: Light 6CO2 + 6H2O à C6H12O6 + 6O2 (Moran 2006) The raw materials needed for photosynthesis are carbon dioxide from the air (taken in through the leaves) and water, usually from the soil (taken in through the roots). The two combine initially to produce simple sugars and oxygen.
The veins in a leaf transport nutrients and water where they are needed and chloroplasts are in a plant’s mesophyll cells, which is where photosynthesis takes place. 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2 is the formula for the photosynthesis chemical reaction (Carter, 2013). There are actually two steps to the photosynthesis process: in order to convert energy into chemical, a reaction to light takes place within the thylakoid membrane. Beta-carotene, Chlorophyll and other various pigments that are vital to the light reaction are systematized into specific groups within the thylakoid membrane;
Selecting variables Independent variable: • Distance of the lamp (cm) This variable needs to be changed to observe its affect on the rate of photosynthesis. • Rate of Sodium bicarbonate (gram) This variable needs to be changed to see how the different rates of Sodium bicarbonate affect the rate of photosynthesis. Dependent variable: • Oxygen bubbles produced per 5 minutes When the distance between the plant and the source of light is increase, then the amount of bubbles produced will decrease as photosynthesis works better with more light. Different rate of Sodium Bicarbonate will affect the rate of photosynthesis. As Sodium bicarbonate increased,
A plant has a unique photosynthetic pigment. The leaves of this plant appear to be reddish yellow. What wavelengths Red and Yellow An outcome of this experiment was to help determine the relationship between wavelengths of light and the oxygen released during photosynthesis As a research scientist you measure the amount of ATP and NADPH consumed by the Calvin cycle in 1 hour cyclic electron flow Assume a thylakoid is some how punctured so that the interior of the thylakoid is no longer separated from the stroma the synthesis of ATP Describe the calvin cycle in general terms The Calvin cycle is a metabolic pathway found in the stroma of the chloroplast in which carbon enters in the form of CO2 and leaves in the form of sugar. Describe the figure Describe the relationship between the light reactions and the calvin cycle ATP and NADPH During photosynthesis visible lights has enough energy to excite electrons. split a water molecule into hydrogen and oxygen.
Photosynthesis and respiration are complete opposites, the only similarities is that they both produce energy. In photosynthesis the energy is produced when this reaction happens Sunlight Hydrogen + carbon dioxide Oxygen + Glucose 6CO2 + 6H2O C6H12O6 + 6O2 Glucose is made up of carbon, hydrogen and oxygen atoms. Glucose made by the process of photosynthesis may be used in three ways: 1. It can be converted into chemicals required for growth of plant cells such as cellulose 2. It can be converted into starch, a storage molecule, that can be converted back to glucose when the plant requires it 3.
Through a process called photosynthesis, energy obtained from light is converted into chemical energy to be used by the plant as a source of sustenance. Along with carbon dioxide and water, plants use the sun energy to make sugar. There are two types of photosynthesis, oxygenic photosynthesis and anoxygenic photosynthesis. In order to understand photosynthesis you have to understand the site where it occurs. Chloroplast is where the process occurs.
Carbon dioxide is pulled from the environment outside of the plant and used as a part of photosynthesis to acquire energy and to run life-sustaining processes. As a byproduct of all this work and of this carbon dioxide collection, oxygen is released back into the environment. This process aids human in two ways. First, it removes harmful (to humans) carbon dioxide from the outside air, and secondly, it creates new oxygen for humans to breathe. The second plant process created from light is photomorphogenesis.
Photosynthesis and Cellular Respiration Abstract In order for plants to live, they must have an energy source. This energy source is achieved through two metabolic processes known as cellular respiration and photosynthesis. These two reactions can be affected by a series of environmental factors and in this lab pH levels are being experimented on in order to see the effects of pH on oxygen production in photosynthesis and oxygen consumption in cellular respiration. To conduct this experiment, an enclosed apparatus was used and a number of leaf disks were used to represent the reaction of photosynthesis and cellular respiration. Introduction All organisms and their individual cells need a source of energy and air supply in order to maintain life.
Light energy from the sun is converted into chemical energy in the form of glucose. Photosynthesis occurs in a series of reactions but the overall equation is: 6CO2 + 6H2O + energy C6H12O6 + 6O2. Energy is stored in the glucose until the plant releases it by respiration. Respiration is the process in which energy stored in glucose molecules is released in the form of ATP. Respiration complex process containing 4 reaction stages, but can be summarised as: C6H12O6 + 6O2 6CO2 + 6H2O + ATP.
Introduction: Cellular Respiration is a process in which glucose is broken down to produce energy in the form of ATP. One of the products of cellular respiration is carbon dioxide. As cells produce carbon dioxide during cellular respiration, it is carried by the blood cells to the lungs where it is exhaled. To be able to test the rate of carbon dioxide, we use Bromothymol Blue, a chemical indicator that changes color as the pH of a solution changes. In a neutral solution, such as water, Bromothymol Blue is blue in color.
