Label the Parts of an Animal Cell worksheet with a word box for students to identify cell structures.

Let's solve this step-by-step by identifying and labeling the parts of the animal cell shown in the diagram.

Step 1: Understand the Diagram

The image is a labeled diagram of an animal cell, with lines pointing to various organelles and structures. There are 14 blank labels (7 on the left, 7 on the right) that need to be filled in using the word box provided at the bottom.

The word box contains these terms:

- Ribosome
- Lysosome
- Nucleus
- Mitochondria
- Cell membrane
- Flagella
- Cytoplasm
- Nucleolus
- Cilia
- Golgi apparatus
- Centrioles
- Cytoskeleton
- Peroxisome
- Secretory vesicle
- Rough endoplasmic reticulum
- Smooth endoplasmic reticulum

We’ll match each structure to its correct label based on its appearance and location in the cell.

Step 2: Identify Each Structure

Let’s go from top to bottom, starting with the left side of the diagram (left column), then the right side (right column).

---

#### Left Side (from top to bottom):

1. Top-left arrow – Points to cilia (hair-like projections).
✔ Label: Cilia

2. Second from top – Points to mitochondria (bean-shaped, red with folds).
✔ Label: Mitochondria

3. Third from top – Points to rough endoplasmic reticulum (purple, folded network with small black dots = ribosomes).
✔ Label: Rough endoplasmic reticulum

4. Fourth from top – Points to nucleus (large pink circle with a dot inside).
✔ Label: Nucleus

5. Fifth from top – Points to nucleolus (small pink dot inside nucleus).
✔ Label: Nucleolus

6. Sixth from top – Points to Golgi apparatus (stacked pink sacs near nucleus).
✔ Label: Golgi apparatus

7. Bottom-left – Points to flagellum (long tail-like structure).
✔ Label: Flagella

---

#### Right Side (from top to bottom):

1. Top-right – Points to cell membrane (outer boundary of the cell).
✔ Label: Cell membrane

2. Second from top – Points to smooth endoplasmic reticulum (green, tubular network without ribosomes).
✔ Label: Smooth endoplasmic reticulum

3. Third from top – Points to lysosome (small red circle, often involved in digestion).
✔ Label: Lysosome

4. Fourth from top – Points to peroxisome (small green sphere).
✔ Label: Peroxisome

5. Fifth from top – Points to centrioles (two small purple cylinders).
✔ Label: Centrioles

6. Sixth from top – Points to secretory vesicle (small pink bubble near Golgi).
✔ Label: Secretory vesicle

7. Bottom-right – Points to cytoskeleton (network of fibers throughout cytoplasm, supporting shape).
✔ Label: Cytoskeleton

---

Step 3: Final Labels

Now, fill in the blanks accordingly:

#### Left Column (top to bottom):
1. Cilia
2. Mitochondria
3. Rough endoplasmic reticulum
4. Nucleus
5. Nucleolus
6. Golgi apparatus
7. Flagella

#### Right Column (top to bottom):
1. Cell membrane
2. Smooth endoplasmic reticulum
3. Lysosome
4. Peroxisome
5. Centrioles
6. Secretory vesicle
7. Cytoskeleton

Bonus: What About Ribosomes?

- Ribosomes are small black dots on the rough ER. They’re not directly pointed to by a line, but they are part of the "Rough endoplasmic reticulum" label.
- So, they are already included in the "Rough endoplasmic reticulum" label.

---

✔ Final Answer Summary:

| Left Side | Right Side |
|----------|------------|
| Cilia | Cell membrane |
| Mitochondria | Smooth endoplasmic reticulum |
| Rough endoplasmic reticulum | Lysosome |
| Nucleus | Peroxisome |
| Nucleolus | Centrioles |
| Golgi apparatus | Secretory vesicle |
| Flagella | Cytoskeleton |

This completes the labeling of all parts of the animal cell! 🧬
