PPT-Photosynthesis Why is it important to the plant?

The general Process Step One absorb sunlight Step Two turn sunlight into usable energy Step Three Use energy to produce biomolecules Leaf Pigments Light Absorption and Reflection Why Leaves are Green. *. 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. 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. . 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.. 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 . 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:. ENERGY IN THE CELL. ENERGY IN THE CELL. ENERGY CONVERSIONS.

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. Click . here. to watch a short film introduction to ponds. . Ponds are often surrounded by plant life and have green algae, lilies, and pondweed growing in them. . Scientists who study the relationship between living things (Ecologists) often need to know why one type of plant lives in one place and another in a different place.. And Respiration of Plants.

First, _______________ strikes the leaf, passes into the leaf, and hits a ______________ inside an individual cell. . 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 . 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! .
