Down
  1. 1. Hollow tubes of tubulin that provide structural support and serve as intracellular tracks.
  2. 2. (two words) Flattened stacks of membranes that modify, package, and distribute molecules.
  3. 3. (two words) Double membrane surrounding the nucleus.
  4. 4. (two words) ER region with ribosomes, site of protein synthesis.
