Rate of Photosynthesis Aim: To investigate the effects of light intensity on photosynthesis. Background: Photosynthesis is a process that plants undergo to produce glucose. The plant then uses the glucose to produce energy which the plant needs to sustain life. The chemical formula for photosynthesis is: Sunlight 6CO2 +6H2O → C6H12O6 + 6O2 Chlorophyll The plant requires light‚ carbon dioxide and water to partake in photosynthesis. Photosynthesis

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

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

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

Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If the

Is photosynthesis important for life? Is photosynthesis important for green plant‚ animal‚ Earth and human? I believe that photosynthesis is major on make fresh air and make the plants own food. I believe that photosynthesis is important for life because the fresh air from the chlorophyll is doing photosynthesis. Plants also make food and oxygen. Then plants is doing photosynthesis‚ it must have sunlight to make their own food and oxygen. The equation about photosynthesis basically is CO2 +

Photosynthesis notes -sunlight brings energy to Earth -the energy in sunlight is packaged in photons -the photosystems in the thylakoid membrane capture photons -pigments in the photosystems have an antenna complex that actually grabs the photons -chlorophyll b captures the photons and transfers the energy to chlorophyll a (the reaction center) -when the reaction center receives the energy it donates an electron -the donated electron will move down the electron transport system (ETS) -ETS

PHOTOSYNTHESIS (How do the light dependent and light independent reactions provide food for a plant?) Why? How important are plants to life on Earth? Could life as we know it continue if there were no plants? Read on the find out why plants are truly the cornerstone of life.
