Cell worksheet for 7 - 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. We are given a list of 9 organelles to label:

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

We need to match each structure in the diagram with its correct name and number.

#### Step-by-Step Identification:

- Pink oval with a yellow dot inside: This is the Nucleus (1), and the small yellow dot inside it is the Nucleolus (2).
- Blue outer layer: This is the Cell membrane (4).
- Green stacked structures: These are the Endoplasmic Reticulum (6) — rough ER, since ribosomes are attached.
- Orange stacked structure: This is the Golgi Apparatus (7).
- Pink folded structures: These are Mitochondria (8) — they have a double membrane and inner folds.
- Yellow round dots: These are Lysosomes (5).
- Small black dots scattered around: These are Ribosomes (9).
- Blue background: This is the Cytoplasm (3).

Now, let’s assign the labels correctly.

#### Labeling the Top Diagram:

From the image:
- The topmost box pointing to the nucleus → 1. Nucleus
- Inside the nucleus → 2. Nucleolus
- Outer blue boundary → 4. Cell membrane
- Green stacks → 6. Endoplasmic Reticulum
- Orange stack → 7. Golgi Apparatus
- Pink folded shapes → 8. Mitochondria
- Yellow round blobs → 5. Lysosome
- Tiny dots → 9. Ribosome
- Blue area surrounding organelles → 3. Cytoplasm

Bottom Diagram: Plant Cell

This is a plant cell. The list includes:

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

Note: Plant cells have a rigid cell wall, large central vacuole, and chloroplasts.

#### Step-by-Step Identification:

- Large purple structure in center: This is the Vacuole (7).
- Green oval structures: These are Chloroplasts (5) — unique to plant cells.
- Blue structures with folds: These are Mitochondria (4).
- Stacked orange structure: This is the Golgi Apparatus (3).
- Network of membranes: Endoplasmic Reticulum (6).
- Small dots: Ribosomes (1).
- Blue background: Cytoplasm (2).
- Purple oval with a dot inside: Nucleus (8).
- Outer green border: This is the Cell wall (not listed, but visible). However, it's not in the list, so we ignore it unless asked.

#### Labeling the Bottom Diagram:

From the image:
- Large central purple structure → 7. Vacuole
- Green ovals → 5. Chloroplasts
- Blue folded structures → 4. Mitochondria
- Orange stacked structure → 3. Golgi Apparatus
- Network of membranes → 6. Endoplasmic Reticulum
- Small dots → 1. Ribosome
- Background → 2. Cytoplasm
- Purple nucleus → 8. Nucleus

✔ Final Answer:

#### Top Diagram (Animal Cell):

| Label | Name | Number |
|-------|--------------------|--------|
| 1 | Nucleus | 1 |
| 2 | Nucleolus | 2 |
| 3 | Cytoplasm | 3 |
| 4 | Cell membrane | 4 |
| 5 | Lysosome | 5 |
| 6 | Endoplasmic Reticulum | 6 |
| 7 | Golgi Apparatus | 7 |
| 8 | Mitochondria | 8 |
| 9 | Ribosome | 9 |

#### Bottom Diagram (Plant Cell):

| Label | Name | Number |
|-------|--------------------|--------|
| 1 | Ribosome | 1 |
| 2 | Cytoplasm | 2 |
| 3 | Golgi Apparatus | 3 |
| 4 | Mitochondria | 4 |
| 5 | Chloroplasts | 5 |
| 6 | Endoplasmic Reticulum | 6 |
| 7 | Vacuole | 7 |
| 8 | Nucleus | 8 |

🔍 Explanation:

- Animal cells lack a cell wall, chloroplasts, and a large central vacuole.
- Plant cells have a cell wall, chloroplasts (for photosynthesis), and a large central vacuole for storage and maintaining turgor pressure.
- Both share common organelles: nucleus, mitochondria, ER, Golgi, lysosomes (in animals), ribosomes, cytoplasm.

This labeling exercise helps reinforce understanding of eukaryotic cell structure and differences between plant and animal cells.
