Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However‚ in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration‚ we need to understand what

CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis At the same

Photosynthesis and cellular respiration go hand in hand‚ but there are differences of the two that most people overlook. Without either of these processes though‚ the human species wouldn’t exist. Along with every other plant or animal. Photosynthesis starts off the cycle‚ with light energy being trapped within the cell and transported into the chloroplast. Water and carbon dioxide follow the similar route of the light energy and as so is collected into the chloroplast. Photosynthesis tends to take

Abstract The process of photosynthesis can be summarized as the photoautotroph consumption of carbon compounds as food and release of oxygen compounds as waste. The methods to measure the rate of photosynthesis are various. One method utilizes CO2 sensors to measure photoautotrophs CO2 intake under various luminescent environments. An elementary method utilizes H2O and NaHCO3 (Sodium Bicarbonate) for submersion of deoxygenized photoautotroph specimens to measure the release rate of oxygen compounds

Cellular Respiration vs. Photosynthesis To obtain energy needed for life‚ organisms depend on the processes of cellular respiration and photosynthesis. Though they share the same function of changing energy from one form to another‚ there are many differences between cellular respiration and photosynthesis in regard to the input and output molecules‚ energetics‚ cellular location‚ and ecological importance. The chemical equations of cellular respiration and photosynthesis are opposites. The reactants

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

Photosynthesis vs. Solar Cells When the subject of solar energy is discussed both the ideas and processes of photosynthesis and solar cells are the basis of these conversations. While both are processing or converting light into energy‚ which will be explained further‚ it is the type of energy that is vastly different. Photosynthesis as a process used by certain plants to convert the suns energy into food. When the electromagnetic energy from the sun reaches a green plant the chlorophyll

plant. Plants and trees cover about thirty percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves to make sugar from carbon dioxide‚ or CO2‚ which is in the
