Julian was investigating different ways to grow plants. He had already tested a homemade greenhouse, different fertilizers in soil, and several other methods. For his next trial, he wrapped a moist paper towel around pea seeds, placed them in a clear plastic bag, created an opening in the bag for air, and taped the bag to his window. In just a few days, his seeds had begun to sprout like the one shown in this image.
What conclusion can Julian draw about pant growth based on his last investigation?
