PPT-Photosynthesis 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 2 is produced as a waste product and the light energy used is stored as chemical energy. *. 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). Lab. 5: Photosynthesis. Lab. 5: Photosynthesis. Leaves float in water due to presence of air (air spaces) in the leaf. . How does one get them to sink?. Lab. 5: Photosynthesis. Put leaf discs under vacuum . 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. Bryanna Wolfe. ECE 2320. October 2012. Start Here. Objective:. . When you get hungry you might decide to raid the cookie jar or ask your mom to make you a sandwich. You do this because humans and animals get energy from the foods they eat. 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. (see student textbook, pages 17 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:. . Photosynthesis. . Process. = plant cells use light energy to rearrange water and carbon dioxide molecules into sugar . molecules. Oxygen is a by-product (leftover, waste product). Energy now stored in the sugar. Agenda. Textbook Reimbursement (TBR). Process . Frequently Asked Questions. 2. 2015-2016 Updates. The legislature replaced the term textbook with “curricular materials”. “Curricular materials” are defined in IC 20-18-2-2.7 as . 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. 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.. 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.
