PPT-Photosynthesis Notes

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. 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. 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. . Photosynthesis. OB48.

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..
