Abstract |
|
This science fair experiment involved placing bean and radish seeds in a hostile, artificial environment, which contained hydrogen peroxide as a source of free radicals. Vitamin A, C and E were added to these groups of seeds to study their protective effects as antioxidants. The purpose of this project was to determine which type of vitamin is most effective for protecting plant cells against free radicals. Results indicated that in all seed germination trials, vitamin A was consistently the vitamin that allowed the most seed germination. In the radish seed trials, the seeds exposed to hydrogen peroxide had the least percentage of germination. This experiment demonstrated the adverse effects of free radicals on seed germination, and the beneficial effects of antioxidants. Other factors that may have influenced seed germination were discussed. This experiment is very relevant to our daily lives as the relationship between free radicals and antioxidants has a possible application towards a healthy lifestyle.
