EXTRA CREDIT!!! MAKE YOUR OWN FLASH CARDS BASED UPON WHAT YOU HAVE LEARNED ABOUT CELLS animal vs. plant cells cell structures & functions Minimum of 12 QUALITY flash cards required for EC!! Due THURSDAY
WHAT IS A CELL? CHALLENGE: What are the similarities and differences between PLANT and ANIMAL cells?
Microscope Protocol Have the arm of the microscope facing you. Clean off the eyepiece, stage glass and objectives with lens paper before beginning. Always start on low power. Course focus, then fine focus. Put what you’re observing in the center of the field of view before moving up to medium power. Click the medium power objective into place. Fine focus. Center the specimen. Click the high power objective into place. Fine focus. Put on low power before removing the slide.
Microscope Sketches Pencil sketches only, please. Use the circle makers to outline each sketch. Label your sketches!
Animal Cells Prepare a “cheek cell” slide. Put a drop of water on a clean slide Gently scrape the inside of your cheek with a clean toothpick Mix the toothpick with the drop of water on the slide. Slowly, from a 45 degree angle, lower a coverslip. Place a drop of methylene blue next to the edge of the coverslip. Draw it under the cover slip by placing a piece of paper towel against the other side of the cover slip. Make careful drawings of several cheek cells. Label your drawing (what it is AND the structures you see).
Plant Cells Make a slide of one Elodea leaf. Gather one leaf from the front of the room Cover with a cover slip Make a careful drawing of the Elodea cells. You should draw a number of cells. Label your drawing (what it is AND the structures you see).
Mystery Slides Observe slide A Make careful drawings of the cells Label your drawing (what it is AND the structures you see). Repeat with slide B
Analysis Questions 1. What structures or features are common to all cells? 2. How do the cells of plants differ from the cells of animals? Cite SPECIFIC detail from the lab in your answer. 3. Looking at the “mystery” slides, could you quickly determine if the cells were plant cells or animal cells? Cite how using specific details from the lab.
