PPT-Photosynthesis Obtaining Energy

Photosynthesis converts light energy from the sun into chemical energy in the form of organic compounds through a series of reactions known as biochemical pathways Autotrophs use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds . Autotrophs. :. Organisms that are capable of producing/creating their own food. Photoautotrophs. – sunlight drives the energy production process. Chemoautotrophs. – can extract energy from an inorganic substance. Energy . and Life. Plants and some other types of organisms are able to use light energy from the sun to produce food.. Autotrophs. : organisms such as plants, which make their own food. Heterotrophs. Textbook pages 97 – 103. Photosynthesis . process used by plants using light energy to create sugar (glucose, C. 6. H. 12. O. 6. ) from carbon dioxide (CO. 2. ) and water (H. 2. O). oxygen gas (. O. 1. ENERGY AND LIFE. OBJECTIVES: 8.1. Explain where plants get the energy they need to produce food.. Describe the role of ATP (adenosine . triphosphate. ) in cellular activities.. 2. Energy is the ability to do work.. Unit 3 . Think back to Energy Transfer…. Living things use energy for . Growth. Repair. Reproduction. Metabolism. The collection of reactions that occur in a cell . Metabolism. Involves either:. . Why Study Photosynthesis?. *All food webs start with photosynthesis!*. Photosynthesis is arguably the most important biological process on earth because of two key chemical reactions. Liberating oxygen:. And Respiration of Plants. By: Annette Miles. Photosynthesis is a process by which plants turn energy from the ____ into _______ or _______________. . sun. glucose. carbohydrates. First, _______________ strikes the leaf, passes into the leaf, and hits a ______________ inside an individual cell. . Photosynthesis . process used by plants using light energy to create sugar (glucose, C. 6. H. 12. O. 6. ) from carbon dioxide (CO. 2. ) and water (H. 2. O). oxygen gas (. O. 2. ) is produced as a waste product and the light energy used is stored as chemical energy. 8-1: Energy & Life. What is energy?. The ability to do work.. What is the difference between autotrophs & heterotrophs?. . Autotrophs = make their own food. . Heterotrophs = can’t make their own food; must eat other organisms. Autotrophs. : any organism that can make their own food.. Photoautotrophs. : use light energy. Chemoautotrophs. change inorganic chemicals such as hydrogen sulfate into chemical energy. 2. Important structures. Refer to . pg. . 83-92 . in . Holtzclaw. , . Ch. 10 in Campbell and media resources. . Refer . to . pg. . 297. -299 . in . Holtzclaw. , Lab . Inv. 5 . in . Lab Manual. Try This!. Where does the biomass of a tree primarily come from?. Chemical Energy and ATP. Energy is the ability to do work.. Your cells are busy using energy to build new molecules, contract muscles, and carry out active transport.. Without the ability to obtain and use energy, life would cease to exist.. Autotrophs. – organisms use can make their own food. Some. autotrophs capture light energy from the sun in the process of photosynthesis. Heterotrophs. – obtain energy from the foods they consume. Cellular Respiration:. During the respiration reaction glucose bonds are broken and the carbon is released to form CO2. . (Use the NAMES of the molecules) According to your equation, the process of cellular respiration uses ____________________ and ___________________ to produce ________________________, ___________________ and release ____________________..
