Part I
Photosynthesis and Respiration

3. Photosynthesis is the ability of green plants to convert _______________energy into stored chemical energy.
Solar 1

4. Photosynthesis takes place in the ________which contains green pigment called ___________
Chloroplast
Chlorophyll 2

5. In addition to sunlight, photosynthesis needs _________ and __________ to work
Carbon Dioxide
H2O 3

6. Photosynthesis produces sugar, water, and ___________.4

7. Stored energy from photosynthesis is in the form of __________
Glucose 5

8. Sugar created by photosynthesis maybe converted to _____________for longer term storage.
Carbohydrates (starch) 6

9. Starch - 1. A naturally abundant nutrient carbohydrate, (C6H10O5) found chiefly in the seeds, fruits, tubers, roots, and stem pith of plants, notably in corn, potatoes, wheat, and rice.

10. Carbohydrates - Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals. These compounds are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually in the ratio 1:2:1.

11. The process of breaking down stored energy is ______________.7

13. Plant growth mostly takes place at _____________?
Night 8

14. In order to break down the stored sugars, plants must produce chemicals called___________?
Four plant enzyme groups exist:
Proteases - break long protein chains into smaller amino acid chains and eventually into single amino acids
Amylases - reduce polysaccharides to disaccharides: lactose, maltose, and sucrose
Lipases - break triglycerides into individual fatty acids and glycerol
Cellulases - digest specific carbohydrate bonds found in fiber 9

15. The equation for respiration is the ___________of photosynthesis.
Opposite 10
