Unit 6 Objectives Chapter 4 Understand the basic tenets of the cell theory Understand the implications of how the surface-to-volume ratio constrains cell size Contrast the general features of prokaryotic and eukaryotic cells Be able to distinguish the organelles and structures typical of eukaryotic plant and animal cells Describe the nucleus of eukaryotes with respect to structure and function Describe the organelles associated with the endomembrane system, and tell the general function of each List several surface structures of cells and tell how they help cells survive Describe the cytoskeleton of eukaryotes and distinguish it from the endomembrane system Discuss the various mechanisms that enable a cell to move Chapter 5 Understand the essential structure and function of the plasma membrane Familiarize yourself with the main membrane proteins and their functions in a cell Know the forces that cause water and solutes to move across membranes passively (without energy) Distinguish between substances that move by simple diffusion and by facilitated diffusion Know the mechanisms by which substances are moved across membranes against a concentration gradient Understand the importance of osmosis to all cells including hypo-, hyper- , and isotonic solutions Understand how material can be imported into or exported from a cell by being wrapped in membranes
