PPT-2016 Ch 10: Photosynthesis

Chapter 10 Photosynthesis From Topic 29 Essential idea Photosynthesis uses the energy in sunlight to produce the chemical energy needed for life Nature of science Experimental designcontrolling relevant variables in photosynthesis experiments is essential 31. *. 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). 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. Photosynthesis. OB48. Describe, using a word equation, how plants make their own food through photosynthesis.  . OB49. Show that starch is produced by a photosynthesising plant.  . OB50. Investigate the growth response of plants to . Leaf Disc Assay. F Block. Photosynthesis Lab. . An Educational Slide Created By Squade. . (Andy, Alex, Colin, Jordyn). Summary of Findings . In this lab, the effects of plant photosynthesis were investigated by comparing the rates of photosynthesis of two plants, spinach and kale. The rate of photosynthesis was measured the number of leaf cutouts on the surface per minute. These floating leaf cutouts show that oxygen, a product of photosynthesis is produced. We found that the rate of photosynthesis for the spinach leaves was 8.6 cutouts per minutes, 1.4 less than that of the kale leaves (10 cutouts per minute.) This difference could be a result the different amounts of light absorbing chlorophyll present in each leaf, or a difference in vascular tissue sizes, which may affect the plant’s ability to absorb water for photosynthesis.. 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. . 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. What is the . ideal combination of factors . for the . maximum . rate of photosynthesis? . enough light. . enough carbon dioxide. . ideal temperature . (not too hot or cold). How is the rate affected if one of these factors is . Refer to . pg. . 83-92 . in . Holtzclaw. , . Ch. 10 in Campbell and media resources. . Refer . to . pg. . 297. -299 . in . Holtzclaw. , Lab .

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! . Lauren . Kendle. Winter Ecology. Spring 2012. Background Information. An analysis of 60 species indicated that there were photosynthetic processes in the . bark. Aspen Trees had the highest level of bark chlorophyll . 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.
