Investigate the impact of environmental factors on plant growth

Briefly describe the pigments used in photosynthesis, where these pigments are located in the plant, and what these pigments do. Define both absorption spectrum and action spectrum, and describe the purpose of using a spectrophotometer to determine the absorption spectrum and how that correlates to the action spectrum. Be sure to discuss how the spectrophotometer allows the identification of the pigment solutions.

Construct a bar graph in excel with your mung bean results. Please include appropriate labels and titles. See attached data and inculde the graph here.

The parentheses represent the answer choices for the blank(s). The independent variable is (the amount of light the plants recieve, the amount of chlorophyll in the plant leaves). The dependant variable is (the amount of light the plants recieve, the amount of chlorophyll in the plant leaves).

irections: Answers must be in essay form. Outline form is not acceptable. Labeled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read each question completely before you begin. An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, Seedings were germinated on moist paper towels at 20°C for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. CUMULATIVE OXYGEN CONSUMPTION O Variety A 7"C - Variety A 17e O Variety B 7°C • Variety B 17°C 20 40 Time (min) 60 8. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD*. Predict he most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction. v + , N - C (qu) Oxygen Consumption
