Across
  1. 2. Selectively controls what enters and leaves the cell.
  2. 6. Produces ribosomes inside the nucleus.
  3. 9. Jelly-like substance where organelles are suspended and reactions occur.
  4. 10. Stores water, nutrients, and waste; helps maintain turgor pressure in plants.
  5. 11. Contains digestive enzymes that break down waste and worn-out organelles.
  6. 13. Rigid outer layer that supports and protects plant cells.
  7. 14. Modifies, sorts, packages, and ships proteins and lipids.
  8. 16. endoplasmic reticulum that has membrane network with ribosomes that modifies and transports proteins.
  9. 17. Produces ATP through cellular respiration; the cell's "powerhouse."
Down
  1. 1. Long whip-like structures used for cell movement.
  2. 2. Site of photosynthesis in plant cells.
  3. 3. Membrane-bound sac that transports materials within the cell.
  4. 4. Site of protein synthesis.
  5. 5. Stores DNA and controls the cell's activities.
  6. 7. Provides support, shape, and movement for the cell.
  7. 8. endoplasmic reticulum that produces lipids and detoxifies harmful substances.
  8. 12. Short hair-like structures that move substances across the cell surface.
  9. 15. Breaks down hydrogen peroxide and detoxifies harmful substances.
