Design Experiment Ecology - effect of acid rain on plat growth - Assignment Example These substances are highly toxic to the living world and directly affects plant and other small organisms thereby, indirectly influence the proliferation of other organisms as well. The present study is designed to understand the effect of acid on plant growth. The study requires 2-3 weeks. The amount of acid added to water, for watering the plant is inversely related to the growth of the plant, which is calculated as the height of the plant. Excess of acid adversely affects the physiology of the plant which should be displayed in the form of pigmentation of the plant, more yellow leaves should appear in the plant which is treated with higher acid concentration as compared to the plant treated with less concentration of acid and with tap water. Hence, survival of the plant is directly related to the concentration of the acid given to the plant. The process will also demonstrate the appropriate pH of water required for the plant growth. Make two acidic solutions with two different concentrations, using water and H2SO4. pH is measured with the help of a pH strip. Adjust the pH of one of the solutions as pH = 2 while adjust the pH of the other solution as pH = 4. Pour equal amount of water/ acid solution simultaneously in all the three sets, A, B and C. Plant A should be provided with an acidic solution of pH 2 and plant B should be provided with the acidic solution of pH 4 while plant C should be provided with same amount of tap water. Growth of the plants was monitored and recorded on a regular basis with the help of measuring tape. The experiment continued for two weeks and observations were recorded in the following table for the comparative analysis of the impact of acid on the growth of plants. Control plant, C was watered with tap water and its growth was also recorded in the following table- Acidification of rain-water occurs
