||Germination is the process in which a plant grows, roots, and sprouts. Germination starts with imbibition, it occurs when a dry seed absorbs water and begins to swell. Water softens the outer layer of seed. Then it uses its stored food supply to fuel the beginning of growth. The root sprouts downward because of gravity. Then using photosynthesis and cellular respiration, it creates the resources and uses them to grow.
||How does the amount of sugar in the water affect the rate of germination?
||If the amount of granulated sugar in the water increases, then the rate of germination will take longer. We think this because it will take longer and more effort for the plant to break the extra sugar down.
||Using the buckwheat seed, we will put 10 seeds in separate trays. Fill one tray with water and, then the next with water and 1/2 teaspoon of sugar. Lastly, we will put 1 teaspoon of sugar in another tray. We will label the seeds in the tray. After 1 week we will measure the growth of each seed in cenimeters and record it. Then, we will compare each of the seeds and the different amounts of sugar.
