Across
  1. 3. – Large sac in plant cells that stores water, nutrients, and waste.
  2. 6. – Colorless plastid that stores starch, lipids, or proteins.
  3. 8. – Network of protein fibers that gives shape, support, and movement to the cell.
  4. 11. – Green pigment in chloroplasts that captures light energy.
  5. 12. – Group of plant organelles that make or store food.
  6. 13. – Stacks of thylakoids.
  7. 15. – Structures involved in organizing microtubules during cell division.
  8. 16. – Rigid outer layer that supports and protects plant cells.
  9. 17. – Flattened sacs inside chloroplasts where light reactions occur.
Down
  1. 1. – Provide mechanical strength to the cell.
  2. 2. – Fluid around the thylakoids where the Calvin cycle occurs.
  3. 4. – Organelle where photosynthesis occurs.
  4. 5. – Thin protein threads that support cell shape and movement.
  5. 7. – Thick protein tubes that help with shape and movement.
  6. 9. – Short, hair-like structures for movement or moving materials across a surface.
  7. 10. – Long, whip-like tail used for cell movement.
  8. 14. – Plastid that stores pigments giving color to fruits and flowers.
