PPT-Phenomenal Photosynthesis

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. – 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. Maya Angelou is an American author and poet. She has published seven autobiographies, three books of essays, and several books of poetry, and is credited with a list of plays, movies, and television shows spanning more than fifty years. She has received dozens of awards and over thirty honorary doctoral degrees. Angelou is best known for her series of seven autobiographies, which focus on her childhood and early adult experiences. The first, I Know Why the Caged Bird Sings, tells of her life up to the age of seventeen, and brought her international recognition and acclaim.. By . Ms. Megan Black. Photosynthesis. Photosynthesis is the process of making food by plants. The essential ingredients in making this food are sunlight, the chlorophyll that is present in green plants, water and carbon dioxide in the air. . 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. 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:. Leaf Disc Assay. A Block. Spinach (Control). Arugula.

Ms. . Albu. B Block. Photosynthesis Lab Findings. We tested the photosynthetic rate of leaf discs of spinach (control) to arugula (experimental) under a 100 watt lamp. Spinach had a higher rate of photosynthesis. 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! .
