Interactive worksheet for identifying cell organelles in animal and plant cells.

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

---

Top Diagram: Animal Cell

This is an animal cell, identifiable by the absence of a cell wall, chloroplasts, and a large central vacuole. It has a nucleus and various organelles.

We are given the following list:
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 label to the correct structure in the diagram:

- Nucleus (1) – The large pink structure in the center with a yellow dot inside.
- Nucleolus (2) – The small yellow sphere inside the nucleus.
- Cytoplasm (3) – The blue gel-like substance filling the cell, surrounding all organelles.
- Cell membrane (4) – The outer boundary of the cell (thin line around the cell).
- Lysosome (5) – Small round yellow structures (often shown as vesicles).
- Endoplasmic Reticulum (6) – Green stacked structures; rough ER has ribosomes on it (small dots), smooth ER does not.
- Golgi Apparatus (7) – Orange, stack-like structure (often curved or flattened sacs).
- Mitochondria (8) – Pink oval structures with inner folds (cristae).
- Ribosome (9) – Tiny black dots on the rough ER or floating freely.

#### Labeling the Top Diagram (Animal Cell):

From the image:
- Top left: Nucleus
- Inside nucleus: Nucleolus
- Around nucleus: Endoplasmic Reticulum (green)
- Orange stack: Golgi Apparatus
- Pink oval: Mitochondria
- Yellow circles: Lysosome
- Thin lines: Ribosome (on rough ER)
- Blue background: Cytoplasm
- Outer edge: Cell membrane

Bottom Diagram: Plant Cell

This is a plant cell, identifiable by:
- A rigid cell wall (outer green layer)
- Chloroplasts (green oval structures for photosynthesis)
- A large central vacuole (purple structure)

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

Now identify each part:

- Ribosome (1) – Tiny dots on the rough ER or free-floating.
- Cytoplasm (2) – Yellow/orange gel-like material inside the cell, outside the vacuole.
- Golgi Apparatus (3) – Pink stack-like structure.
- Mitochondria (4) – Blue oval structures with internal folds.
- Chloroplasts (5) – Green oval structures with internal stacks (grana).
- Endoplasmic Reticulum (6) – Network of membranes (orange lines near nucleus).
- Vacuole (7) – Large purple structure taking up most of the cell.
- Nucleus (8) – Purple oval structure near the top.

#### Labeling the Bottom Diagram (Plant Cell):

From the image:
- Large central structure: Vacuole
- Outer green layer: Cell wall (not listed, but implied)
- Green ovals: Chloroplasts
- Blue ovals: Mitochondria
- Pink stack: Golgi Apparatus
- Orange network: Endoplasmic Reticulum
- Purple oval: Nucleus
- Tiny dots: Ribosome
- Yellow area: Cytoplasm

Final Answer (Labeling Guide)

#### Top Diagram (Animal Cell):
1. Nucleus – Central pink structure
2. Nucleolus – Yellow dot inside nucleus
3. Cytoplasm – Blue background
4. Cell membrane – Outer boundary
5. Lysosome – Small yellow spheres
6. Endoplasmic Reticulum – Green stacked membranes
7. Golgi Apparatus – Orange stack
8. Mitochondria – Pink folded ovals
9. Ribosome – Tiny dots on ER

#### Bottom Diagram (Plant Cell):
1. Ribosome – Tiny dots
2. Cytoplasm – Yellow region
3. Golgi Apparatus – Pink stack
4. Mitochondria – Blue ovals
5. Chloroplasts – Green ovals
6. Endoplasmic Reticulum – Orange network
7. Vacuole – Large purple structure
8. Nucleus – Purple oval

✔ Summary:
The task is to correctly label the organelles in both animal and plant cells using the provided keys. Key differences:
- Plant cells have cell wall, chloroplasts, and large central vacuole.
- Animal cells have lysosomes, centrioles (not shown here), and no cell wall or chloroplasts.

You can now fill in the blanks on the worksheet using these labels!
