3. – Large sac in plant cells that stores water, nutrients, and waste.
6. – Colorless plastid that stores starch, lipids, or proteins.
8. – Network of protein fibers that gives shape, support, and movement to the cell.
11. – Green pigment in chloroplasts that captures light energy.
12. – Group of plant organelles that make or store food.
13. – Stacks of thylakoids.
15. – Structures involved in organizing microtubules during cell division.
16. – Rigid outer layer that supports and protects plant cells.
17. – Flattened sacs inside chloroplasts where light reactions occur.

1. – Provide mechanical strength to the cell.
2. – Fluid around the thylakoids where the Calvin cycle occurs.
4. – Organelle where photosynthesis occurs.
5. – Thin protein threads that support cell shape and movement.
7. – Thick protein tubes that help with shape and movement.
9. – Short, hair-like structures for movement or moving materials across a surface.
10. – Long, whip-like tail used for cell movement.
14. – Plastid that stores pigments giving color to fruits and flowers.
