Swaggy Seeds

Project by group dmsstiemspring2021

Explore A plant needs the right conditions to grow, which include the right temperature, moisture, and light. Seeds are still alive when not growing which is called being dormant, they travel and disperse by using animals and weather to their advantage. The seed starts to germinate, water has been absorbed, and activates the embryo and it becomes active. When the leaves have grown to the place where they can see sunlight, they start to photosynthesize. If there is not enough light, the plant will die. The questions I still have are, can seeds live without one of the right conditions and also, how does a plant know how to photosynthesize and when to do it. Buckwheat seeds normally take 3-4 days t grow with warm soil. They need a decent amount of water to grow and when they grow, they get long fast. Buckwheats seeds are not very tolerant to shade and grow faster in the sun.
Research Question How does changing the amount of water affect how fast a seed germinates?
Predictions We think the seed with the most amount of water will germinate the fastest. The seed with the least amount of water will germinate the slowest. The more water a seed has to take in, the more the seed can take in and germinate faster.
Experimental Design We will put 5 mL, 7 mL, and 15 mL of water in both bags with the seed. Everyone is assigned an amount of water per seed and they observe and water their respective seed. When the seed starts to germinate we will count how long it took for it to happen. We will take the number of days, average them and that will be our numbers.
Conclusion The seed given the most water will germinate the quickest because the more water you give a seed, gives it a better chance/opportunity to germinate quicker. In our investigation, when we gave a seed 15ml of water, after the first day of measuring, the average root was 3.7cm. On the other hand when we have a seed only 5ml of water, the average root was 2.9cm. This is because moisture essentially brings seeds out of their dormant states. If a seed needs water to germinate, the more water you give it, the faster chance it has to germinate. Although if you give a seed a less amount of water it will take longer to process, because it has less resources/water.
