What happens to plants that are exposed to lead water? My group and I’s hypothesis for this question was if there is an increase of lead water then the basil plant’s growth might decrease. Our hypothesis was partially correct. One of the experimental plants grew 2 inches and the other one decreased in size by .25 cm, meaning that our hypothesis was partially correct. The big finds were that the lead water effects plants differently than it would to humans. For humans drinking a certain amount depends on what happens to your body. When the lead is in your system, the calcium competes with the lead water to be absorbed by the body. It affects kids more than it does to adults. Drinking the lead can affect several parts of you body and it could affect your future. The lead sticks to your red blood cells (doctors will test your blood for proof if you were exposed to lead water) then it moves into the soft tissues of the liver and the lungs. If the lead is absorbed into your bones it can stay there for decennary. It will eventually spread and circulate in your blood when a bone is broken or when a woman’s pregnant; it will potentially poison the mother and the baby (Popular Science 2019). For plants on the other hand is a totally different affect. Plants watered with lead water have a 50 50 percent chance that it will grow or decrease in size (Daisy Hernandez Ect all). The lead water is affecting people in Flint Michigan. The water is being combined by lead and making dirty water that can cause a lot of harm if consumed. The plant that we used to conduct for our experiment was the basil plant. The basil plants food chain can be affected if the basil is not there. The basil is the producer, meaning that it contains 100% of energy because it makes its own food using photosynthesis . The next one in line is the Japanese beetle, the beetle is the primary consumer. Its has 10% of energy. After that comes the grackles. It has 1% of the energy. It is the secondary consumer. The last one in the food chain is the tertiary consumer meaning it has 0.01% of energy and it eats anything dead. If the human impact continues to happen there would be less of us to eat the basil and to reproduce it. It is valuable for humans to know about our investigation so that they know not put themselves in danger of watering their plants with lead water. A further investigation that we could do is see how it affects sea creatures like a fish; so that we can compare the results of the other experiments we have conducted.
