1 AGENDA 10/19-10/20 2. Experiment CATALYST (10 minutes, individual work): 1. Fill out this chart: Step Location Product (s) Examples Lactic Acid Fermentation Alcohol Fermentation

2 CATALYST (10 minutes, individual work): 1. Fill out this chart: Step Location Product (s) Examples Lactic Acid Fermentation Cytoplasm Lactic acid, NAD+, ATP Alcohol Fermentation Cytoplasm Alcohol, CO 2, NAD+, ATP Muscle cells, cheese, yogurt Yeast cells (beer, bread)

3 CATALYST part 2 (10 minutes, individual work): Draw this slide with me When you draw a slide think about: Scale (relative size) Details in shape You don t necessarily need to draw every little detail in the field of view

4 Introduction Write in paragraph form, restating the question at the beginning. 1. What are unique structures that are in plant cells? 2. What are the three unique structures for? 3. What is unique about animal cells? 4. What is the purpose of this lab? 5. State your hypothesis (your hypothesis should answer the experimental question of the lab: what are the differences between plant an animal cells? Describe what you predict you will see in a plant cell and an animal cell.

5 Procedure Elodea Investigation 1. Get 1 elodea leaf, place in center of slide, place coverslip over 2. Look under microscope at 4X. Move slide to find a good section of cells. 3. Look using 10X objective. Use fine focus. Move slide if desired X, draw what you see in your field of view. Make sure it is detailed. Include at least 3 cells in your drawing. 5. Label the cell with any known structures. Cheek Cell Investigation 1. Using a toothpick, gently scrape against the inside of your cheek. 2. GENTLY roll the end of the toothpick on the center of the slide. 3. Put one drop of methylene blue. Carefully place slide cover. Look under microscope at 4X. Move slide to find a good section of cells. 4. Look using 10X objective. Use fine focus. Move slide if desired X, draw what you see in your field of view. Be detailed. Include at least 3 cells in

6 Lab #3 Plant and Animal Cell Lab Data Elodea 40X Human cheek cells 40x

7 Lab #3 Plant and Animal Cell Lab PROCESSING TASK (10 minutes, individual work): Discussion Write in paragraph form, restating the question at the beginning. 1. Restate hypothesis. (rewrite your entire hypothesis) 2. Did your results support/refute your hypothesis? (did your data support or not support your hypothesis?) 3. Summarize your data in 2 sentences. 4. What are the differences between plant and animal cells? 5. See question on lab sheet 6. How do those differences support the different functions of plants vs animal cells? 7. What are 3 possible errors you could have made? (make sure this is well thought out) MAKE OR BREAK STAMP 8. What are some future experiments you could conduct using this as a jumping off point? MAKE OR BREAK STAMP

8 PROCESSING TASK (10 minutes, individual work): References (let s write it together) Book Author s last name, first initial. Year of publication. Title. Publisher, location. Number of pages.
