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 structures: These are Ribosomes → Label 9
- Blue gel-like area surrounding organelles: This is the Cytoplasm → Label 3

So, from the diagram:
- Top two boxes (pointing to nucleus and nucleolus): 1 (Nucleus) and 2 (Nucleolus)
- Right side: 6 (ER), 7 (Golgi), 8 (Mitochondria), 5 (Lysosome)
- Left side: 9 (Ribosome), 5 (Lysosome) again (if there are multiple), and 3 (Cytoplasm)
- Bottom: 4 (Cell membrane)

> ⚠️ Note: The cytoplasm fills the entire interior space, so it should be labeled in the background area.

Bottom Diagram: Plant Cell

This is a plant cell. It has all the organelles of an animal cell plus:
- A cell wall
- Chloroplasts
- A large central vacuole

Given list for labeling:

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

Now, identify each part:

#### Labeling the Plant Cell:

- Green oval structures with dots inside: These are Chloroplasts → Label 5
- Large purple structure in center: This is the Vacuole → Label 7
- Blue double-membraned structures: These are Mitochondria → Label 4
- Stacked pink structure: This is the Golgi Apparatus → Label 3
- Network of tubules (orange): This is the Endoplasmic Reticulum → Label 6
- Purple oval with a dot inside: This is the Nucleus → Label 8
- The small dot inside is the nucleolus, but not listed separately here
- Tiny dots on the ER: These are Ribosomes → Label 1
- Yellow gel-like substance: This is the Cytoplasm → Label 2
- Rigid outer boundary (green): This is the Cell Wall → Not in the list, but implied as structural feature

Wait — the list doesn’t include "Cell Wall", so we only label what’s in the list.

So, from the diagram:
- Top: 8 (Nucleus), 6 (ER)
- Right: 3 (Golgi), 4 (Mitochondria), 1 (Ribosome), 2 (Cytoplasm)
- Left: 5 (Chloroplasts), 7 (Vacuole)

Note: The vacuole is large and central, so it’s clearly labeled.

| Box Position | Label |
|--------------|-------|
| Top left (nucleus) | 1. Nucleus |
| Top right (nucleolus) | 2. Nucleolus |
| Right side (ER) | 6. Endoplasmic Reticulum |
| Below ER (Golgi) | 7. Golgi Apparatus |
| Below Golgi (mitochondria) | 8. Mitochondria |
| Bottom right (lysosome) | 5. Lysosome |
| Left side (ribosome) | 9. Ribosome |
| Left bottom (lysosome) | 5. Lysosome |
| Bottom (cytoplasm) | 3. Cytoplasm |
| Outer edge (cell membrane) | 4. Cell membrane |

> 💡 Tip: Some labels may repeat if there are multiple organelles (e.g., lysosomes or mitochondria).

#### Plant Cell (Bottom Diagram):

| Box Position | Label |
|--------------|-------|
| Top (nucleus) | 8. Nucleus |
| Top right (ER) | 6. Endoplasmic Reticulum |
| Right side (Golgi) | 3. Golgi Apparatus |
| Below Golgi (mitochondria) | 4. Mitochondria |
| Bottom right (ribosome) | 1. Ribosome |
| Bottom (cytoplasm) | 2. Cytoplasm |
| Left (chloroplasts) | 5. Chloroplasts |
| Center (vacuole) | 7. Vacuole |

🔍 Key Differences Between Plant and Animal Cells:

| Feature | Plant Cell | Animal Cell |
|--------|------------|-------------|
| Cell wall | Yes (rigid, cellulose) | No |
| Chloroplasts | Yes | No |
| Large central vacuole | Yes | Small or absent |
| Shape | Fixed, rectangular | Irregular, round |
| Lysosomes | Present (less common) | Present (common) |
