Cell Structure and Functions
  1. What is the cell theory
    1. Every living organism is made up of one or more cells, the smallest organism are single cells.
      1. Cells are the functional units of multicellular organisms, and all cells arise from preexisting cells.
    2. What are the basis attributes of cells?
      1. Cells are small because they must exchange materials with their surroundings by diffusion, a slow process that require the interior of the cell to be close to the plasma membrane.
        1. Cells use DNA as a genetic blueprint and RNA to direct protein synthesis based on DNA.
          1. There are two fundamentally different types of cells:Prokaryotic cells are small and lack membrane-enclosed organelles. Eukaryotic cells have a variety of organelles, including a nucleus.
      2. What are the major features of eukaryotic cells?
        1. lack an organized nucleus and other membrane-bound organelles.
          1. Prokaryotic DNA is found in a central part of the cell called the nucleoid.
            1. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.
            2. What are the major features of prokaryotic cells?
              1. Eukaryotic cells have an internal cytoskeleton of protein filaments that shapes the cell, transports and anchors organelles, and allows cells to move.
                1. Some eukaryotic cells have cilia or flagella, extensions of plasma membrane that contain microtubules in a characteristics pattern.
                2. DNA is contained within the nucleus, surrounded by the double membrane of the nuclear envelope.
                  1. The genetic material is organized into strands called chromosomes, wich consis
