  5. sex pili
  1. a A temporary, foot-like extension of a cell, used for locomotion or engulfing food
  2. b in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP
  3. c elongated, hollow appendages that pull 2 cells together prior to DNA transfer from one cell to the other found in bacterium
  4. d membrane-bound sac containing digestive enzymes that can break down proteins, nucleic acids, and polysaccharides
  5. e A threadlike linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information

5 Multiple Choice Questions

  1. The complex of DNA and proteins that makes up a eukaryotic chromosome. When the cell is not dividing, it exists as a mass of very long, thin fibers that are not visible with a light microscope.
  2. double membrane perforated with pores that control the flow of materials in and out of the nucleus
  3. System of internal membranes within the cytoplasm. Membranes have the presence of ribosomes; functions in transport of substances such as proteins within the cytoplasm
  4. in a bacterium, stored nutrients for later use
  5. in a prokaryotic cell, the portion composed of the plasma membrane, the cell wall and the gycocalyx

  2. endoplasmic reticulumSystem of internal membranes within the cytoplasm. Membranes have the presence of ribosomes; functions in transport of substances such as proteins within the cytoplasm

          

  3. smooth endoplasmic reticulumSystem of internal membranes within the cytoplasm. Membranes have the presence of ribosomes; functions in transport of substances such as proteins within the cytoplasm

          

  4. glycocalyxA layer of exopolysaccharide fibers on the surface of bacterial cells which may be involved in adherence to a surface. Sometimes a general term for a bacterial capsules; if compact called capsule and if diffuse, called slime layer
