Comparing Prokaryotic and Eukaryotic Cells Integrated Science 1 N ame: 11/13 Per. Background Ever since the first microscope was used, biologists have been interested in studying the cellular organization of all living things. After hundreds of years of observations by many biologists, the cell theory was developed. The cell theory states that the cell is the structural and functional unit of living things. One of the way cells are classified is by the structures they contain. In plant and animal cells, both similarities and differences exist with respect to structure. In this investigation, you will compare the structures of a typical bacteria cell, plant cell and animal cell. Focus Questions • How are plant, animal, and bacterial cells alike? How are they different? First, read this article: http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/cells/cellsrev1.shtml Analysis and Conclusion Questions Directions: Answer the following questions, using complete sentences. 1. Define and give an example from the reading of prokaryotic and eukaryotic cells. 2. Based on this article, describe the differences you observed between prokaryotic and eukaryotic cells. 3. Based on this article, describe the similarities you observed between prokaryotic and eukaryotic cells. 4. If you were given a slide containing living cells of an unknown organism, how would you identify the cells as either plant or animal? *note: be very thorough and include in your answer a full description of every structure, and characteristic, one would expect to be able to use to differentiate between plant and animal cells. 5. Define diffusion, explain why it is important for the cell, and give an example.
