Biology Chapter 3 Name___________________ Date_____________ Hr____ Cells Alive Scavenger Hunt Open your web explorer and type in the following address: www.cellsalive.com Using the choices on the bar at the top of the web page, choose Contents, Cell Biology, then choose Cell Model. 1. Describe the difference between prokaryotic and eukaryotic. Prokaryotic cells: _______________________________________________________ _____________________________________________________________________ Eukaryotic cells: ________________________________________________________ _____________________________________________________________________ Click on Prokaryotic Cell Model, then Start Animation to answer the following questions. Click on a term to get a description of that term and its function in the bacterial cell. Position the cursor over a label to find out its location in the cell. 2. What type of cell is a bacterial cell? (prokaryotic or eukaryotic) ____________________ 3. What is the function of the capsule? _________________________________________ 4. What is the function of the flagella? _________________________________________ 5. Draw one large simplified bacteria cell on the page beneath the word bank box. Be sure to label the parts listed in the word bank box below. Cell envelope Capsule Ribosome Nucleic acid (nucleoid) Cytoplasm Flagella Pili 1 Click on View Plant/Animal Cell to answer the following questions. Choose Animal Cell. Position the cursor over a label to find out its location in the cell. Click on a term to get a description of that term and its function in the animal cell. 6. Which organelle is responsible for directing the cell? This organelle also houses the genetic material in the cell. _____________________________________________________________________ 7. Which organelle is responsible for packaging and transporting macromolecules? _____________________________________________________________________ 8. Which organelle is responsible for holding chemicals needed for digestion in the cell? _____________________________________________________________________ 9. Which organelle is responsible for synthesizing proteins? _____________________________________________________________________ 10. Which organelle is responsible for moving proteins throughout the cell? _____________________________________________________________________ 11. Which organelle is responsible for providing energy to the cell? _____________________________________________________________________ 12. Which organelle is responsible for storing waste? _____________________________________________________________________ 13. Which organelle is responsible for providing a barrier allowing only certain things in and out of the cell? _____________________________________________________________________ 14. Which organelle is the site of ribosome production? _____________________________________________________________________ Now choose Plant Cell to answer the following questions: 15. Which organelle provides a barrier and maintains the rigidity of the plant cell? _____________________________________________________________________ 16. Which organelle is responsible for housing the chlorophyll in a plant? _____________________________________________________________________ 17. Which organelle is responsible for storing waste and water in a plant? _____________________________________________________________________ 2 Draw a simplified animal cell on the page beneath the word bank box.
