Let’s label the parts of the animal cell step by step.

We’ll go from top to bottom on both sides, matching each line to the correct organelle using the Word Box.

---

Left Side (Top to Bottom):

1. Topmost left box → Points to hair-like structures on top → These are Cilia
2. Second from top left → Points to oval-shaped organelles with inner folds → These are Mitochondria
3. Third from top left → Points to the jelly-like substance filling the cell → This is Cytoplasm
4. Fourth from top left → Points to small dots scattered in cytoplasm → These are Ribosomes
5. Fifth from top left → Points to the network around the nucleus with dots → This is Rough endoplasmic reticulum
6. Sixth from top left → Points to the dark spot inside the nucleus → This is the Nucleolus
7. Seventh from top left → Points to the large central sphere → This is the Nucleus
8. Eighth from top left → Points to a stack of curved sacs → This is the Golgi apparatus
9. Bottom left box → Points to tiny round vesicles near Golgi → These are Secretory vesicles

Right Side (Top to Bottom):

1. Topmost right box → Points to the outer boundary of the cell → This is the Cell membrane
2. Second from top right → Points to thread-like fibers in cytoplasm → This is the Cytoskeleton
3. Third from top right → Points to another mitochondrion (same as left) → Mitochondria
4. Fourth from top right → Points to small circular organelles → These are Lysosomes
5. Fifth from top right → Points to smooth tubular network → This is Smooth endoplasmic reticulum
6. Sixth from top right → Points to two short cylinders at right angle → These are Centrioles
7. Seventh from top right → Points to a small bubble-like structure → This is a Peroxisome
8. Bottom right box → Points to long whip-like tail → This is the Flagella

Now let’s double-check we used all words from the Word Box:

Word Box has:
- Ribosome ✔
- Lysosome ✔
- Nucleus ✔
- Mitochondria ✔ (used twice — that’s okay, there are multiple)
- Cell membrane ✔
- Flagella ✔
- Cytoplasm ✔
- Nucleolus ✔
- Cilia ✔
- Golgi apparatus ✔
- Centrioles ✔
- Cytoskeleton ✔
- Rough endoplasmic reticulum ✔
- Peroxisome ✔
- Secretory vesicle ✔
- Smooth endoplasmic reticulum ✔

All 16 terms are used correctly.

Final Answer:
Left side (top to bottom): Cilia, Mitochondria, Cytoplasm, Ribosome, Rough endoplasmic reticulum, Nucleolus, Nucleus, Golgi apparatus, Secretory vesicle
Right side (top to bottom): Cell membrane, Cytoskeleton, Mitochondria, Lysosome, Smooth endoplasmic reticulum, Centrioles, Peroxisome, Flagella
