CH.4.  CH.4. Cell Structure and Function  CH. 4. Cell Structure and Function     Objectives :    1.    Understand the basic tenets of the cell theory.    2.    Understand the essential structure and function of the cell membrane.     3.    Contrast the general features of prokaryotic and eukaryotic cells.     4.    Describe the nucleus of eukaryotes with respect to structure and function.     5.    Describe the organelles associated with the endomembrane system, and tell the general            function of each.     6.    Contrast the structure and function of mitochondria and chloroplasts.     7.    Describe the cytoskeleton of eukaryotes and distinguish it from the endomembrane system.     8.    List several surface structures of cells and tell how they help cells survive.     Key Terms : cell plasma membrane nucleus nucleoid cytoplasm ribosomes prokaryotic cells eukaryotic cells surface-to-volume ratio cell theory wavelength compound light microscope transmission electron microscope scanning electron microscope phospholipid cell membrane lipid bilayer fluid mosaic model  prokaryotes eubacteria

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
