Acid Rain's Effect On The ET50 Time Of Plants

Decent Essays
In this lab the effect of changing the pH of water that leaf disks were submerged into to find the effect on the ET50 time of plants. The hypothesis was that if the pH is closer to a normal water pH than the ET50 time will be the smallest. This lab was conducted to see what different variables change the amount of time needed for photosynthesis to occur(ET50) . This is important because of acid rain being present in the world with climate change and the effect it can have on plants which has large tolls. Previous studies have shown that acid rain and a change in pH can have damaging effects on plants. One study, showed that, acid rain destroyed the chloroplast of soybeans the location of photosynthesis in plants which disrupted photosynthesis
