USING WHAT YOU JUST LEARNED FROM THE ABOVE TRIALS TRY AND CREATE THE BEST
ENVIRONMENT FOR SEEDS TO SPROUT.
8. How many seeds were you able to sprout over the course of 5 days? What were your controls?
9. Which control do you think is the most important? Least important? WHY
TRY SOME OF THE DIFFERENT SEEDS AND SEE WHAT HAPPENS
10. Do you notice any changes/differences when you changed to a different type of seed? If you did, why do
you think there are differences between the seeds?
Review:
11. What is the first step in seed germination?
12. The is where the stored food is located within the seed.
13. is the process in which a plant uses energy from light to produce food.
14. is the process in which a plant break down food to release energy.
15. Almost % of our oxygen is produced during photosynthesis.
16. Where does photosynthesis take place?
17. A plant will carry and carbon dioxide to the leaves during the day so that the plant can conduct and produce sugar.
18. The plant will store the excess food it produces in the .
