1) Discuss the importance of magnification and resolution in microscopy. How are the magnification and resolution of a light microscope different from that of an electron microscope? 2) Which microscope would you use to study the following? a) the changes in shape of a living human white blood cell b) the finest details of the surface texture of a human hair c) the detailed structure of an organelle in a liver cell 3) State the cell theory?...

Cell Organelles and their Functions This unit we are learning about cells and the organelles contained within. In this Discussion, we’ll focus on the functions of the various organelles and cell structures: Cell membrane | Mitochondria | Plant cell wall | Plant chloroplast | Nucleus | Lysosomes | Nuclear envelope | Rough endoplasmic reticulum | Golgi apparatus | Smooth endoplasmic reticulum |Cytoskeleton | Cilia and flagella Select four of the organelles or structures above and briefly describe where each is...

Classify each statement as to whether it represents a piece of evidence that supports the endosymbiont theory of the evolution of mitochondria and chloroplasts from prokaryotes. Some organellar genes have migrated to the nucleus. Evidence for the endosymbiont theory Does not support endosymbiont theory Some organelle proteins are encoded in the nucleus. Organelles do not have flagella. Mitochondrial rRNA genes are most similar to the rRNA gene of a bacterium. Organelle translation is inhibited by antibiotics that inhibit prokaryotic translation...

Chapter 4: A Tour of the Cell 5. Smooth endoplasmic reticulum (SER) lacks _, which gives it a "smooth" appearance. 6. True or false: If false, make it a correct statement. The smooth endoplasmic reticulum con- tains many enzymes that allow it perform functions like detoxify circulating drugs. 7. Use Figures 4.14 (page 65 of your textbook) and 4.17 (page 67 of your textbook) to answer the following question. Place the following steps in the order in which they occur...

You are working in a laboratory producing new antibiotics for human and veterinary use. One compound with potential value inhibits the action of prokaryotic ribosomes. The compound, however, was shown to inhibit the growth of animal cells in culture. What is one possible explanation for its effect on animal cells? Applications A research laboratory in pharmaceutical company is studying environmental factors that would inhibit the growth of Archaea. One question they have is if adding of antibiotic penicillin would be...

1. A student uses iodine to visualize cells under the light microscope. Iodine stains starch deep blue and glycogen granules dark brown. Observation of the cells reveals the presence of cell walls, dark brown granules, mitochondria, and a prominent nucleus. If the chemical composition of the cell wall is determined, which of the following molecules would MOST likely be the major constituent? A. cellulose B. chitin C. lignin D. peptidoglycan 2. Which of the following statements is the MOST compelling...
