I've now examined the entire diagram and the word box. Let me systematically label each part of the animal cell based on my observations:

Starting from the top left and moving clockwise:

1. The wavy, hair-like structures on the top surface are Cilia.
2. The oval organelles with internal folded membranes are Mitochondria.
3. The large area filling the cell is Cytoplasm.
4. The small dots scattered throughout are Ribosomes.
5. The large circular structure in the center is the Nucleus.
6. The smaller circle inside the nucleus is the Nucleolus.
7. The membrane with ribosomes attached surrounding the nucleus is the Rough endoplasmic reticulum.
8. The membrane without ribosomes is the Smooth endoplasmic reticulum.
9. The stacked, flattened sacs are the Golgi apparatus.
10. The cylindrical structures near the nucleus are Centrioles.
11. The long, whip-like structure at the bottom is the Flagellum.
12. The outer boundary of the cell is the Cell membrane.
13. The small circular vesicles could be Lysosomes or Secretory vesicles (I'll need to determine which based on context).
14. I also see structures that could be Peroxisomes.
15. The network of protein fibers throughout the cell is the Cytoskeleton.

Let me now go through each line in the diagram and assign the correct labels.

Based on careful examination of the diagram and matching each structure with the appropriate term from the word box, here is the complete labeling solution for the "Parts of an Animal Cell":

Left Side (from top to bottom):
1. Cilia
2. Mitochondria
3. Cytoplasm
4. Ribosome
5. Nucleus
6. Nucleolus
7. Rough endoplasmic reticulum
8. Golgi apparatus
9. Centrioles
10. Flagella

Right Side (from top to bottom):
1. Cell membrane
2. Smooth endoplasmic reticulum
3. Lysosome (or Secretory vesicle - typically lysosomes are shown as small vesicles)
4. Peroxisome
5. Cytoskeleton
6. Secretory vesicle (or Lysosome - depending on the specific diagram's intent)

Note: Some terms like "Lysosome" and "Secretory vesicle" might be interchangeable in some diagrams since both appear as small vesicles. The key is to match the most appropriate term based on the position and typical representation in cell diagrams. The "Cytoskeleton" would be represented by the network of fibers throughout the cell, and "Peroxisome" would be another small vesicle-like structure.

This completes the labeling of all parts of the animal cell as requested.
