Across
  1. 7. Membrane-bound structures found in eukaryotic cells that have specialized functions.
  2. 9. A protective layer external to the plasma membrane in plant cells, bacteria, fungi, and some protists. In the case of plant cells, the wall is formed of cellulose fibers embedded in a polysaccharide-protein matrix.
  3. 11. A type of cell lacking a nucleus and membrane-enclosed organelles; Bacteria.
  4. 13. Chromosome-containing organelle of a eukaryotic cell.
  5. 14. An organelle that serves as the site of cellular respiration. The powerhouse.
  6. 15. An extensive membranous transport network in eukaryotic cells.
  7. 16. The outer membrane of the cell; the plasma membrane.
Down
  1. 1. A sac-like organelle used to store a variety of substances.
  2. 2. The fundamental structural unit of life.
  3. 3. Stacks of flat membranous sacs that modify, sort, and package products of the E.R.
  4. 4. A photosynthetic organelle found only in plants and photosynthetic protists.
  5. 5. The contents of the cell, exclusive of the nucleus. Made of fluid, cytosol, and organelles.
  6. 6. A structure in an animal cell, which are involved in cell division.
  7. 8. Organelle constructed in the nucleus. The site of protein synthesis in the cytoplasm.
  8. 10. A membrane-enclosed bag of enzymes. Digest waste products of the cell.
  9. 12. An organism whose cells contain membrane-bound organelles and a nucleus.
