AGRI 1005 : AGRI 1005 Final Study Guide
Document Summary
Human population growth, flowering plants, domestication and origins of agriculture, the food problem (bourlag reading will help) Important metabolic processes in plants (including crop plants) Autotrophs versus heterotrophs, trophic chain: autotrophs: producers. Use light to make energy-containing organic molecules from inorganic raw materials: heterotrophs: consumers. Require a pre-made source of organic molecules because they cannot manufacture organic molecules from inorganic raw materials on their own. Photosynthesis and respiration: metabolism: metabolic processes include all the chemical reactions and associated energy transfers needed for an organism to grow, maintain itself, reproduce, etc, photosynthesis & respiration are the most fundamental metabolic processes in plants. Stroma (what"s stroma?: respiration: cytoplasm, mitochondria, mitochondrial membranes. Photosynthesis: light reactions take place in the thylakoids of the chloroplast. Involves capture of light energy, initial conversion into chemical energy, and release of oxygen: dark reactions take place in the stroma. These reactions are also referred to as the calvin cycle .
