Light Intensity

Light intensity is based on the assumption that light bulb will emit when current flows. Doubling the voltage doubles the intensity of the light. This is because light is concentrated more. Since more power is measured to measure the intensity of the light, the intensity of the ray is twice the intensity of the ray. Measure the intensity of LDR emission electrons. The current increase is said to be proportional to the potential difference.

At low light intensity, as the light intensity increases, the rate of the light dependent reaction, and therefore photosynthesis, generally increases proportionately (linear relationship). The more photons falling on the leaves, the more ATP and NADPH are produced as the number of ionized chlorophyll molecules increases. Light dependence reaction uses light energy, so it is not affected by temperature change. The photo-dependent reaction of photosynthesis is not affected by temperature change, but the photo-independent reaction of photosynthesis depends on temperature. They are enzyme catalyzed reactions. As the enzyme approaches its optimum temperature, the overall proportion increases. Every time the temperature rises by 10 ° C, it almost doubles. When the optimum temperature is exceeded, as the enzyme degenerates, the rate begins to decrease until it stops.

A series of temperature - independent light - dependent reactions and a series of temperature - independent light - dependent reactions. The first series of ratios called photoreactions can be enhanced by increasing the light intensity (within certain limits), not by increasing the temperature. In the second series called dark reaction, you can increase the speed (within a certain range) by raising the temperature rather than raising the light intensity. This experiment is an investigation of the photosynthetic rate, ie the rate at which plants produce all the organic matter at a rate that only uses light energy and simple inorganic matter (food). The photosynthetic rate depends on environmental factors, especially light available, carbon dioxide level and temperature. The effect of these factors can be experimentally tested by changing one of the factors while keeping other factors constant.

Factors influencing the photosynthetic rate of underwater cotyledons (seed leaves)

Influence of light intensity on photosynthesis of Elodea canadensis I want to know how much light intensity affects photosynthesis of Elodea Camadensa. I decided to do this by measuring the amount of oxygen produced during photosynthesis. Photosynthesis is the process by which all plants make food. In this process, carbon dioxide, water, and light energy are used. It produces oxygen and glucose. - Examine the influence of light wavelength on the photosynthetic rate ==== Prepare a beaker with a method of 250 cm 3 and fill with distilled water. Because distilled water is used, impurities do not destroy photosynthesis. Then take the x cm of erodia and put it in the beaker. Cover the erodia with the big end of the funnel and cover the tip of the funnel cover with a test tube. Then light up the experiment
