Germination is when a seed grows into a new plant. The absorption of water encourages this process to happen. Germination is affected by many external factors. These external factors include water, temperature and light. With Deionized water as the control group, the absorbed water starts the germination. However, with 0.5M CaCl2 as the experimental group, the salt in the solution enables the seeds to grow. It all has to do with Osmosis; the salt concentration solution draws out the little water that is in the seed. According to BBC, osmosis is the diffusion of “water molecules from areas of high water concentration to areas of low water concentration through a selectively permeable membrane.” The seeds with 0.5M CaCl2 did not grow because
