PPT-Light Energy Photosynthesis:

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 . *. Photosynthesis. – process of capturing light . . energy. from the sun to convert water & CO. 2. . . into oxygen and high energy carbohydrates . (food, ex: glucose, starch, & other sugars). 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.. Almost all plants are photosynthetic autotrophs, as are some bacteria and protists. Autotrophs generate their own organic matter through photosynthesis. Sunlight energy is transformed to energy stored in the form of chemical bonds. 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. . 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?. Photosynthesis. - a process used by plants and other autotrophs to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. . *It is the way plants make food! . The light-dependent reaction. The light-independent reaction. Required practical 7: . Use of chromatography to investigate the pigments isolated from leaves of different plants, . eg. , leaves from shade-tolerant and shade-intolerant plants or leaves of different colours.. 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.
