  2. 4. the initial wall laid down by a plant cell
  3. 7. a smooth membrane that surrounds a chloroplast enclosing the stroma
  4. 8. sites of photosynthesis in plant cells
  5. 9. placid containing red and yellow pigments
  6. 10. a family of plant organelles
  7. 12. colorless plastid that stores starch in plants
  8. 13. a gel-like polysaccharide that hold the walls of adjacent cells together
  9. 14. the membrane that surrounds the central vacuoles
Down
  1. 1. the added wall layer, which is more rigid and much thicker
  2. 2. the main hormone of the thyroid gland, responsible for controlling the rate of metabolism in the body
  3. 3. the perforations in the primary and secondary cell walls
  4. 5. large vesicles that are identified as distinct organelles of plant cells because they perform specialized function unique to plants
  5. 6. membrane lying just inside the OBM of a chloroplast
  6. 11. structure of chloroplasts of higher plants formed by thylakoids stacked one on top of the other
