photosynthetic rate. Photosynthesis at low temperatures actually take CO2 more efficiently. The rate of photosynthesis is decreased by higher oxygen concentrations. Lower temperatures inhibit Rubisco and forces this enzyme to to work competitively. Rubisco works competitively because is actually binds itself to oxygen rather than binding to carbon dioxide because of the mere attraction. Therefore, in doing so, this activates photorespiration rather than photosynthesis. Photosynthesis in corn is different

MY BIOLOGY S.B.A Lab #1 Topic: Classification Aim: To classify organisms into groups Apparatus: Method: A list of 10 organisms in my school environment was made and observed. A table was constructed to show the organism and their visible characteristics. Another table was constructed to show the kingdom, phylum and class to which the organisms belong. Observation Organism | Visible Characteristics | Bird | They are vertebrates with a pair of wings. They also have a beak | Cat |

1st Hour 12-4-15 Cellular Respiration and Photosynthesis In my Photosynthesis Lab my group changed the amount of light intensity by increasing the amount of Light Bulbs used (2 per cup), making it Qualitative. By increasing the amount of light bulbs we noticed that the leaf disks floated to the top of the water 2 times as fast. The leaf disks floated to the top because the water put little pockets of CO2 and Oxygen and us putting more light bulbs the Oxygen and CO2 were being ¨put into” the

Science Lab Report. Section 808 Photosynthesis. 19th of October 2012. Introduction Definition: Photosynthesis is the physico-chemical process by which plants, algae and photosynthetic bacteria use light energy to drive the synthesis of organic compounds. In plants, algae and certain types of bacteria, the photosynthetic process results in the release of molecular oxygen and the removal of carbon dioxide from the atmosphere that is used to synthesize carbohydrates (oxygenic photosynthesis) Whitmarsh

The purpose of this lab was to isolate the chloroplast from spinach and measure its size while determining if weed killers would inhibit electron transport. This was done by centrifuging homogenized spinach. After re-suspending the pellet in ice-cold 100 mM Tris (pH 8.0), 0.4 M NaCl, some solution was removed to use for examination under a microscope to estimate the number of chloroplasts in the homogenate and the size of the chloroplast. A series of solutions, some with DCIP, some with Diuron, and

Description of Graph: As shown, yellow light has the fastest rate of photosynthesis out of white, red, and yellow light. The red light has the slowest rate of photosynthesis out of white, red, and yellow light. The white light has the median rate of photosynthesis out of the white, red, and yellow light. Analysis and Conclusion: The hypothesis for the white light experiment was: If white light is shone on the leaf disks in the beaker containing sodium bicarbonate, then the amount of time it takes

5 | Zebra Plant | 4.2 | 7.6 | 6.1 | 3.2 | LAB 1 Journal 1. Transpiration is when water from plants is evaporated into the atmosphere. It usually happens when, during photosynthesis, the plant's stomata is open so that Carbon Dioxide and Oxygen can pass through. When transpiration occurs, not only is the water cycle being executed, but also it pulls water up from the roots into the plant leaves, supplies needed materials for photosynthesis and even cools the leaf 2. my experiement
