PPT-Photosynthesis Rate Results

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. 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. 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 . 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..
