Bean germination

Here is my plan:
Can beans germinate without sunlight? We covered our beans up with paper to see if they would germinate. We did an experiment on the beans to see if they would grow without sunlight. We used soil and water. The gravity pushes the roots and the radicle down. The bean gets water and soil but no sunlight but the seed still splits apart. The bean bursts out of its seed coat to grow. It expand bigger until it's at a normal plants size. The stem and leaves need sunlight but the radicle and roots uses gravity. This happens because when you jump the gravity pushes you down, the same thing happens to the roots and the radicle. The bean germinates
