| Activity #8: The Differences between a Plant Cell and an Animal Cell
Take a look at the transmission micrograph of a plant cell and an animal cell. Page 58-59 text. 1. What are two obvious similarities and differences between those two cells? 2. How large are those two cells (approximately)? 3. Look around the classroom and find the two cell models. One is a plant cell and the other is an animal cell. List two more differences between the cells. Activity #9: Summarizing the parts of Animal and Plant cells Please copy the table below. Use an entire sheet of paper just for the table! Plant, Animal or Both Function Cell wall Cell plasma membrane Nucleus Nucleolus Endoplasmic Reticulum Ribosomes Mitochondria Chloroplasts Lysosomes Vacuoles Activity 10: Specialized Cells It is difficult to describe a typical cell because you will find more of certain organelles in some cells and less in others. A) Why do cells need to specialize? B) A farm or city example from Mr. Liao C) Remove a fresh leaf of anacharis D) Prepare a wet mount E) Warm up the mounted slide with your hand or on the overhead projector F) Examine the cell under low power G) Observe under high power. How many layers does it have (use depth of field)? H) The green dots are chloroplasts- look on page 65. What do chloroplasts do? I) Can you see the chloroplasts move? This is an example of CYTOPLASMIC STREAMING. Why might this be useful? J) Draw 3-4 cells on high power. Label the cell wall, chloroplast, and nucleus (if visible) Activity 11: The Cytoplasm A) What is the cytoskeleton of a cell? What does it do for the cell? B) What are the two parts of an animal cell�s cytoskeleton? C) Mechanisms of cell movements: a. Pseudopods \ b. Flagella = describe using pg. 66-67 text and movie clips c. Cilia / D) What is cytoplasmic streaming? Describe what it is and how you see it as you view the anacharis. Activity 12: Prokaryotic Cells A) What does PROKARYOTIC mean? B) What are some differences between a PROKARYOTE and an EUKARYOTE? Give me at least three differences. C) What is a nucleoid? D) Sketch figure 4.25 (a) of a typical prokaryotic cell. Label the capsule, cell wall, plasma membrane, cytoplasm, and DNA. Activity 13: Review Exercises Please answer Self-Quiz Questions pg. 73 text # 1-3, 5, and 6. |
