Animal Cell Worksheet -Worksheets Library - Free Printable

Let’s go through the cell diagram step by step.

This is a drawing of an animal cell — you can tell because it has no cell wall, no chloroplasts, and includes centrioles (which plant cells usually don’t have).

We need to match each number to the correct organelle or structure. Let’s identify them one by one based on standard biology diagrams:

1 → This points to the outer boundary of the cell → Cell membrane
2 → Small dot inside the nucleus → Nucleolus
3 → The large central sphere containing the nucleolus → Nucleus
4 → Stack of flattened sacs near the nucleus → Golgi apparatus
5 → Wavy lines with dots on them → Rough endoplasmic reticulum
6 → Oval-shaped structures with inner folds → Mitochondria
7 → Pair of cylindrical structures at right angles → Centrioles
8 → Tiny dots scattered in cytoplasm → Ribosomes
9 → Long thin strands radiating from centrioles → Microtubules / Cytoskeleton
10 → Empty-looking oval space → Vacuole (smaller than in plant cells)
11 → Jelly-like substance filling the cell → Cytoplasm

Now let’s write that clearly for the worksheet.

Final Answer:
1. Cell membrane
2. Nucleolus
3. Nucleus
4. Golgi apparatus
5. Rough ER
6. Mitochondria
7. Centrioles
8. Ribosomes
9. Microtubules
10. Vacuole
11. Cytoplasm
