Light Intensity On Photosynthesis

INTRODUCTION Photosynthesis is a chemical process in which plants, algae and certain bacteria produce oxygen and glucose using the energy from the sunlight. This process is important for life because of the oxygen and glucose released; these products are used in many life processes. Photosynthesis takes places in a wide variety of organisms and also comes in different forms; these include a form of photosynthesis that does not produce oxygen which is called anoxygenic and the other form which does is oxygenic (Raven et al., 2014). The types of pigments used to trap light energy are similar for both of these types of photosynthesis but have different arrangement and action, for example in case of plants, photosynthesis primarily takes place in the leaves and the plant leaves cells contain organelles that are called chloroplasts which carry out the process of photosynthesis(Raven et al., 2014). Photosynthesis can be represented using the following balanced equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2, Where: CO2 is carbon dioxide, H2O = water and the light energy is required to produce; C6H12O6 = glucose and O2 = oxygen.…show more content…
During this experiment, the source of light is changed, by decreasing its distance from the plants, from no lamp to 10cm. The rate of photosynthesis should increase and therefore the amount of oxygen bubbles should increase
