Plant Cells Name: Mrs. Strasbaugh/Mrs. Leedy Date: Elodea Leaf Cell Lab Question: What do chloroplasts do? Can they be seen with a microscope? Research: Answer these Pre-lab Questions using your notebook or textbook: 1. Look up and read chloroplast on page 40 of your text book. Thoroughly, with detail, describe a chloroplast. (What is in it, shape, location, etc?) Materials: Elodea leaf dropper glass slide cover slip water Procedure: Read through the questions on the back of this paper so you do not miss making important observations. Carefully, make a wet mount slide of the Elodea leaf by spreading it flat in a drop of water on a slide. Use a cover slip. Observe cells on low, medium and high power. On high power, fine focus, very slowly, up and down to observe the thickness of the cell. Results: Draw a cell on high power only. Remember to record the magnification. Label the cell parts listed by drawing a line (using a straight edge) from the word to the part in your drawing. cell wall cell membrane cytoplasm nucleus vacuole chloroplast Observations: 2. Look for chloroplasts in the cells. Describe what they are doing? 1 Plant Cells Name: Mrs. Strasbaugh/Mrs. Leedy Date: Elodea Leaf Cell Lab Analysis: Answer the following questions using complete sentences. 3. Why do you think the chloroplasts are doing this? 4. Read pages 62 and 63. Summarizing what you’ve read, describe how a chloroplast makes food. 5. Why are chloroplasts important to your life (page 65)? 6. Write the chemical equation for photosynthesis in symbols and in sentence form? + + 7. Is Elodea a prokaryote or a eukaryote? 8. How do you know, give 3 pieces of evidence? Proceed to the Photosynthesis Webquest 2
