Burpee Pea Seeds Lab Report

Discussion
Nine of the Burpee Pea Seeds were tested with tap water that had a pH 8 and nine were tested with a lemon juice and water solution that had a pH of 4. of Between days one through four the acid rain and tap water seeds were alike. The seeds were round and tan. On day two the seed coat became squishy. On day three test one seeds two and three of the acid rain and water began to sprout roots, and all of the seeds in test two and three began to sprout. Seeds one, two, and three in the acid rain test one group’s roots began to curl on day four and the stem was just barely visible in seed one. The water seeds in test one, two and three the stem became visible. The acid rain roots are curled and the tap water roots are not. See appendix five for pictures of the tests daily. Between days five and six the seeds embryo grew and the roots became longer and started spouting …show more content…
The roots are white and fuzzy. Some of the roots grew into the paper towel. On day six the acid rain seeds started to grow mold and their growth rate was halted. On day seven the acid rain roots in tests 2, and three were shriveled and brown. On day eight the tap water seeds had just a touch of mold and their stems were sprouting leaves. On day nine seed one, two, and three in the acid rain group one started to sprout leaves. By day eleven the acid rain seeds were very moldy. On day fourteen seventeen out of the eighteen seeds had leaves. The acid rain seeds were smaller than the tap water seeds. Their roots were curled and the water seeds were not. They were also moldier than the water seeds.
The results from this experiment indicate that acid rain has a negative effect on seeds and how they germinate. The acid in the rain stunts the growth process making the roots and the stem smaller than normal water. The acid rain also causes the roots to curl and shrivel. If a plant has shorter roots that are not as strong the plant can not reach the nutrients
