Plant Nutrients What are the needs of plantsGuided notesPart IPhotosynthesis and RespirationPhotosynthesis is the ability of green plants to convert _______________energy into stored chemical energy.

Solar1Photosynthesis takes place in the ________which contains green pigment called ___________

Chloroplast Chlorophyll2In addition to sunlight, photosynthesis needs _________ and __________ to workCarbon DioxideH2O

3Photosynthesis produces sugar, water, and ___________.

4Stored energy from photosynthesis is in the form of __________

Glucose5Sugar created by photosynthesis maybe converted to _____________for longer term storage.

Carbohydrates (starch)6Starch - 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.

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.The process of breaking down stored energy is ______________.

Plant growth mostly takes place at _____________?

Night8In 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 fiber

9The equation for respiration is the ___________of photosynthesis.
