Cell Organelles activity - Free Printable

Let's solve this step-by-step by identifying and labeling the parts of both animal and plant cells based on the provided diagrams.

Top Diagram: Animal Cell

This is an animal cell. It has typical organelles but lacks a cell wall, chloroplasts, and a large central vacuole (which are present in plant cells).

We are given the following list to label:

1. Nucleus
2. Nucleolus
3. Cytoplasm
4. Cell membrane
5. Lysosome
6. Endoplasmic Reticulum
7. Golgi Apparatus
8. Mitochondria
9. Ribosome

Now, let’s match each structure with its correct label:

#### Labeling the Animal Cell:

- Top center (pink structure): This is the Nucleus → Label 1
- Inside the nucleus, the small yellow circle is the Nucleolus → Label 2
- Blue outer layer: The Cell membrane → Label 4
- Green stacked structures (like pancakes): These are the Endoplasmic Reticulum (ER) → Label 6
- The rough ER has ribosomes on it; smooth ER does not.
- Orange folded structure: This is the Golgi Apparatus → Label 7
- Pink bean-shaped structures: These are Mitochondria → Label 8
- Small yellow spheres: These are Lysosomes → Label 5
- Tiny dots on the green ER and scattered: These are Ribosomes → Label 9
- Blue gel-like area surrounding organelles: This is the Cytoplasm → Label 3

Bottom Diagram: Plant Cell

This is a plant cell. It has all the organelles of an animal cell plus:
- A cell wall (rigid outer layer)
- Chloroplasts (green, for photosynthesis)
- A large central vacuole

Given list:

1. Ribosome
2. Cytoplasm
3. Golgi Apparatus
4. Mitochondria
5. Chloroplasts
6. Endoplasmic Reticulum
7. Vacuole
8. Nucleus

Let’s label accordingly:

#### Labeling the Plant Cell:

- Outer green rigid layer: This is the Cell wall (not in list, but implied) — however, the list doesn't include it, so we skip.
- Large purple structure in the center: This is the Vacuole → Label 7
- Green oval structures (with green granules inside): These are Chloroplasts → Label 5
- Blue bean-shaped structures: These are Mitochondria → Label 4
- Stacked orange structure (similar to Golgi): This is the Golgi Apparatus → Label 3
- Pink network (ER): This is the Endoplasmic Reticulum → Label 6
- Pink nucleus with darker spot: This is the Nucleus → Label 8
- Tiny dots on ER and elsewhere: These are Ribosomes → Label 1
- Yellow gel-like area: This is the Cytoplasm → Label 2

📌 Key Differences Between Animal and Plant Cells:

| Feature | Animal Cell | Plant Cell |
|-----------------------|-------------|------------|
| Cell Wall | No | Yes |
| Chloroplasts | No | Yes |
| Large Central Vacuole | No | Yes |
| Shape | Irregular | Rectangular |
| Centrioles | Yes | No (usually) |

✔ Conclusion: You should now fill in the blank boxes on the diagram using the numbers from the lists as per the above identification.

If you're filling out the worksheet, just write the number corresponding to each part next to the line pointing to that structure.
