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
