NAME_____________________________________________________________________BLOCK__________ Eunice Eukaryote, Cell Doctor M.D PART 1: The following are REAL conditions affecting plant animal and bacterial cells. Try and figure what is going on!! (these are difficult, but give them a try) Case#1 Erythocytes (red blood cells), are much smaller than most human cells, and contain about 270 million hemoglobin molecules, the molecule responsible for carrying oxygen. However, at maturity, they have no nuclei, mitochondria, or any other organelle. Why? Case #3 Pompe’s disease is one of a class of lysosomal storage diseases in which one or more enzymes that are normally found in the lysosomes are defective or absent. In Pompe’s disease, the enzyme designed for breaking down glycogen (starch) is absent. Describe what you would see in the cells of an individual with Pompe’s disease? What danger would this pose for cells in the individual’s body? Case #4 Corn Smut Fungus, a fungus that affects corn plants, gets its energy by eating cellulose, a main component of plant cell walls. What effect would this fungus have on the corn cells? On the plant overall? Why do farmers and livestock not have to worry about infection from this fungus? Case #5 A family of viruses known as the stunt viruses, infect plant cell chloroplasts. Explain what would happen to a plant that was infected by such a virus. Case 9: When plants are fully fed and watered, they often appear to stand straight up. When forgetful students fail to water the plants they begin to wilt. Explain what is happening. What organelle is directly involved? PART 2: 1. Identify the type (plant, animal or bacteria) of cell in the examples on the next page. Circle an identifying characteristic of that particular cell A. B. C.. D. PART 3 Try these cell questions: They will be similar to what you see on a test or quiz. 1. Each of the following is a cell organelle except one. Which one of these is NOT a cell organelle? a) mitochondrion b) lysosome c) cytoplasm d) endoplasmic reticulum 3. What structure is common to ALL cells? a) Chloroplast b) Cell membrane d) Mitochondria c) Cell wall e) Flagella 4. When a large proportion of a cell's ribosomes are attached to the endoplasmic reticulum, it is a sign that the cell is specialized to: a. Manufacture glucose for storage b. Manufacture phospholipids for cell growth c. Perform photosynthesis with high efficiency d. Manufacture proteins for export
