Name Class Date Guided Inquiry How Do Organisms Capture and Use Energy? 1. Your teacher will provide you with two test tubes wrapped in foil. The test tubes contain colonies of Euglena, which are photosynthetic microorganisms. Find the hole in the foil around one of the test tubes. 2. Where do you predict Euglena will be found in each test tube? Record your prediction. 3. Carefully remove the foil from each test tube. Make sure not to shake or disturb their contents. Observe the locations of Euglena in the test tubes, and record your observations. Analyze and Conclude 1. Identify Patterns What pattern do you observe in the distribution of Euglena in the two test tubes? 2. Construct an Explanation How could the pattern you observed in Euglena behavior be useful or beneficial to the organism? Propose a logical explanation. 3. Apply Scientific Reasoning Euglena can also live heterotrophically. If you repeated the experiment with test tubes of Euglena that also contained a food source, do you think the results of your experiment would be the same? Explain your reasoning.
