You will learn about specific cell structures and their function. Procedure: 1. To begin go to www.cellsalive.com 2. Select “Cell Biology” from the left hand menu 3. Visit the “How Big is a…?” section of the site to get a better perspective on the variations of cell size. You should see an image of a person holding a pinhead. Part A. HOW BIG IS A...." Here you will look at objects found on the head of a pin. Your job is to rank them in order of size on the chart below and estimate the length of each (in nanometers, micrometers, or millimeters). The line in the bottom right corner of the screen is used to help you estimate. You do not need to record this information on this sheet. Part B. LABEL DIAGRAMS Next, under Cell Biology, click on Cell Models and select “Bacterial Cell”. In this section you will discover the significance of the bacterial cell and its parts! 4. 5. 2. 1. Explain the function of the labeled parts # 1-6: 1. 2. 3. 4. 5. 6. 3. Now select the “Plant and Animal Cell Animation” link from the top of the page. Once there, click on the Animal Cell and label the following parts below. 1. 12. 2. (the whole thing) = (stringy stuff inside) = 9a. 9b. 3. 7. 4. 11. 5 6. 5. . 8. 7. After looking at the bacteria cell and the animal cell, which is more complex? Circle. 8. Is the animal cell a prokaryote or a eukaryote? Circle. Part C: ANIMAL CELL MODEL For this model, you will need to click on the various parts of the cell to go to a screen that tells you about the parts. Answers to the following questions are found there Animal Cell Model - For this model, you will need to click on the various parts of the cell to go to a screen that tells you about the parts. Answers to the following questions are found there. 1. What do mitochondria do? Sketch each of the following. Mitochondria 2. How big are mitochondria? 3. What does the Golgi Apparatus do? Rough ER 4. What is the difference between smooth and rough ER? Plasma membrane 5. Where specifically is the nucleolus found? 7. What does the cytoskeleton do? 8. Cytosol goes by what other name? Lysosome 9. What is the function of the cytosol? Golgi Apparatus 10. What is the function of the lysosome? 11. What is the main function of the plasma membrane Plant Cell Model - (you will need to return to the "Cell Biology" link to access this page, or hit your back button) . 5. 9 4. 1. . . 9. (outside membrane) 2. (the whole thing) = (stringy stuff inside)= 3. 6. 10. 12. . 8. 7. Plant Cell 1. What is the nucleus seen in both the animal and plant cell made of, what is so important about it? Sketch the following Nucleus 2. What is the specific function of the nucleolus? 3. What are ribosomes involved with? 4. What is the cell wall made of and what is its function? 5. What makes the plant cells green? 6. What is the function of chloroplasts? Chloroplast Vacuole 4. In plant cells, what does the vacuole do? Overview For the chart below, place a check in the box if the cell has that component.
