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

A.    The Basics of Cell Structure 1.     The cell is the smallest unit with the properties of life: metabolism, response to environment,          growth, and reproduction. 2.     The inside of eukaryotic cells are divided into various function compartments like a nucleus.
