Essay / The relationship between light intensity and photosynthesis rate. Study the relationship between light intensity and the rate of photosynthesis. Photosynthesis is important because animals eat food because it is a source of energy. . All living things need a constant supply of energy to grow, reproduce or move. Plants don't eat food, but they do have some in the form of starch in their leaves. The symbolic equation for photosynthesis is as follows: 6 CO2 + 6 H2O-light C6 H12 06 + 6 02. There are four substances necessary for photosynthesis to function properly: Photosynthesis cannot take place without the presence of these four substances. Since light is the factor I am exploring in this investigation, it is the main factor I am looking at. Plants need light for photosynthesis to take place; photosynthesis will not take place in the dark. It is true that the brighter the light, the higher the rate of photosynthesis. Many plants have their leaves spread out so that each leaf receives as much light as possible and the lower leaves are not shaded by those above. I study the effects of light on the rate of photosynthesis. It is possible to do this by measuring the rate of photosynthesis at different light intensities by counting the number of gas bubbles emitted by the plant in a given time. To make the test fair, I will use the same amount of water and the same leaf from the same plant.[IMAGE][IMAGE] [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][ IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE] ][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE ][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][ IMAGE][IMAGE]Test tube light ======== ================================================== ============================ ========================================================= ========================================================== ======================================== ========================== ====================FunnelBeakerplasticinepond weedMethod.I can do this by setting up the diagram above.
