Without light‚ plants would not be able to carry out photosynthesis (McKenney‚ Peffley‚ and Wilmington 49). Photosynthesis is responsible for providing the plant with nutrients it needs to thrive and grow. Without the proper nutrients‚ it is difficult for a plant to continue to live. Therefore‚ photosynthesis is necessary for a plant’s vitality. The goal of this experiment is to observe and identify the impact that light has on a plant. Hypothesis: If light affects photosynthesis in plants‚ then the
