Why Energy the ability to do work Energy cannot be created nor destroyed only transformed Electromagnetic energy sun chemical bond energy heat energy Increase in order. 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 . Define Photosynthesis. The process by which plants manufacture (make) carbohydrates from raw materials using energy from the light.. Word and Chemical equation of Photosynthesis. 6CO. 2. + 6H. 2. O . 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. 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. . Warm up (11-23-15). Explain what you know about plants.. Try to be specific and use scientific terms if possible.. Outline. Objectives. Plant Background Info. Objectives. To gain background information about plants and how they colonized land. 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. 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.

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. What am I and why am I important to life in the ocean?. What Do You Really Know About Plankton?. Name means: “Drifters” or “Wanderers. ”. So. . .are they autotrophs. or heterotrophs?. They can be either one!. 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. 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 . 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.
