PPT-Photosynthesis Lab - Elodea &

Bromothymol Blue Photosynthesis Lab Background In this lab we will investigate the process of photosynthesis We will learn how the amount of light affects photosynthesis To do this we will use. *. 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 . 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 . 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. 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:. . 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 . Cheek Cell. LAB. Microscope Quick Steps. Name the 6 Quick Microscope Check--Steps with your partner.. Start on low power. Turn coarse adjustment knob to lower. Center fine adjustment knob. Check mirror. November 17, 2009. A ___________ is a group of different species that live together in one area.. Community. Population. Organism. Ecosystem. Biome. O. 2 . represents. Glucose. Energy. Carbon dioxide. 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. . 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. 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.
