1. The loss of water. In humans, this happens as sweat.
2. The site of oxygen and water release and carbon dioxide intake in plants.
3. The ATP for the Calvin Cycle comes from _____ I or II, depending on whether the process was cyclic or non-cyclic.
4. Though not exclusively made from G3P, this is a large chain storage molecule for glucose in plants.
5. Plants require this number of ATP to perform the Calvin Cycle and generate G3P.
6. At the end of the Calvin Cycle, the plant must ______ more RuBP molecules to start over with binding CO2.
7. These extremely common plants are C4 plants, meaning they strike a medium balance in managing CO2 intake and H2O loss.
8. CAM plants need the least amount of water, but also grow the most ______.
9. This is how many RuBP are needed to bind 3 carbon dioxide
10. The type of chemical reaction used to produce G3P during the Calvin Cycle
11. This molecule fixes (binds to) carbon dioxide out of the air, for use in the Calvin Cycle.
12. This factor that affects the rate of photosynthesis can be harmful at either very high or very low extremes.
13. Stomata are located on the underside of leaves to minimize this phase change.
14. 18 of these atoms are involved in the Calvin Cycle, in total.
15. C3 plants require large amounts of ______ because they have their pores open the most.
16. Cacti are an example of this type of plant.
17. The number of G3P molecules the plant gets to use as “extra” from the Calvin Cycle
18. At some point, increasing [CO2] will not increase photosynthesis rates because the RuBP has reached its _____ to bind CO2
19. Another term for speed.
20. It is okay, and normal, for plants to release this gas from their pores.
