Cell Diversity Lab The last two exercise you were introduced to the microscope and the cell. This lab builds off of your knowledge of how to use the microscope, its parts, and functions in order to view your specimens. The cell lab your learned about Plant and Animal cells. You learned about the cellular structure of the cells and were able to compare and contrast their structures and functions. In this lab your will be examine a variety of cell types, ranging from prokaryotic cells (cyanobacteria and bacteria) to eukaryotic cells (plant cells and animal cells). You should be able to recognize each of these cell types as well as any subcellular structures visible with the light microscopes. In addition, you should be able to name bacterial types and identify Oscillatoria, Anabaena, and Gloeocapsa. Although this is a virtual lab, try to estimate the size of a cell or organism as seen through the microscope. Please review the cell diversity PowerPoint. Part I: Please watch the YouTube video at the following links to watch the Oscillatoria and Anabaena (There are also YouTube links in Blackboard). Oscillatoria: https://youtu.be/_Rcia-KWHMs Anabaena: https://youtu.be/HKX42psLc0k Draw the Oscillatoria and Anabaena at 400X. Label the following on the appropriate specimens (they may overlap): chlorophyll, filament, heterocyst, and individual cell Oscillatoria (400X)Anabaena (400x) Are the cyanobacteria motile? Does their structure influence their motility? Part II: BACTERIAL SHAPE YouTube link: https://youtu.be/ZRgeh7cN9PQ The image below is https://youtu.be/HKX42psLc0k What do Bacteria and Blue green algae have in common? Part III: Elodea Please watch the YouTube video at the following links to watch Elodea. (There are also YouTube links in Blackboard). Elodea: https://youtu.be/UWbGZMO4o_U Draw the Elodea at High magnification. Label the following on your drawing: Cell wall, Cell membrane, chlorophyll, and vacuole. Elodea (High) What is the purpose of the vacuole in the Elodea? Part IV: Amyloplasts Please watch the YouTube video at the following links to watch a potato and the demonstration of amyloplast storing starch. (There are also YouTube links in Blackboard). The section of the video is between 1:30 and 3: https://youtu.be/eEvS6-gti7M Draw the Elodea at High magnification. Label the following on your drawing: Cell wall, Cell membrane, Amyloplasts, and Starch grains. Potato Amyloplast (High) Describe the process of the storage of starch. Part V: Chromoplasts Please watch the YouTube video at the following links to watch chromoplasts storing color pigments in carrot cells. (There are also YouTube links in Blackboard). Carrot under the microscope: https://youtu.be/eEvS6-gti7M Compare and contrast the chromoplasts and the amyloplast from part V. Part VI: Amyloplasts Please watch the YouTube video at the following link to watch a Ranunculus dicot root cross section demonstration. (There are also YouTube links in Blackboard). Cross Root https://youtu.be/6eQB5tsjzk8 Draw the Ranunculus dicot root cross at High magnification. Label the following on your drawing: Cortex cells, epidermal cells, phloem cells, and Xylem cells. Ranunculus dicot root cross (High) What is the function of the Xylem cells? What is the function of the Cortex cells? Part VII: Paramecium Please watch the YouTube video at the following link to watch a Paramecium. (There are also YouTube links in Blackboard). Paramecium: https://youtu.be/KkaFDWrBM1Y What mode of locomotion does the Paramecium use? Can you identify a contractile vacuole? What is the function of the vacuole? Part VIII: Amoeba Please watch the YouTube video at the following link to watch a Amoeba. (There are also YouTube links in Blackboard). Amoeba: https://youtu.be/7pR7TNzJ_pA How does this one-celled organism move? What is the tern used to describe the cytoplasmic extensions? Part IX: View the following images of prepared slides of neurons, skeletal muscle, and human blood cells. How does the structure of each cell type reflect its function? Part X: PowerPoint Please review the PowerPoint on Cell Diversity in the lab folder. Identify if they are Prokaryotic or Eukaryotic. Also Compare and Contrast the cells
