2Photosynthesis and Respiration Part IPhotosynthesis and Respiration
3Photosynthesis is the ability of green plants to convert _______________energy into stored chemical energy.Solar1
4Photosynthesis takes place in the ________which contains green pigment called ___________ ChloroplastChlorophyll2
5In addition to sunlight, photosynthesis needs _________ and __________ to work Carbon DioxideH2O3
6Photosynthesis produces sugar, water, and ___________. 4
7Stored energy from photosynthesis is in the form of __________ Glucose5
8Sugar created by photosynthesis maybe converted to _____________for longer term storage. Carbohydrates (starch)6
9Starch - 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.
10Carbohydrates - 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.
11The process of breaking down stored energy is ______________. 7
13Plant growth mostly takes place at _____________? Night8
14In 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 acidsAmylases - reduce polysaccharides to disaccharides: lactose, maltose, and sucroseLipases - break triglycerides into individual fatty acids and glycerolCellulases - digest specific carbohydrate bonds found in fiber9
15The equation for respiration is the ___________of photosynthesis. Opposite10
