Animal and plant cell parts worksheet - Free Printable

Let's solve this step-by-step by identifying and labeling the parts of both the animal cell and the plant cell using the provided word banks.

🔬 Part 1: Animal Cell (Top Diagram)

Word Bank:
- cytoplasm
- mitochondrion
- cell membrane
- nucleus
- lysosome

Now, let’s identify each labeled part in the animal cell diagram:

1. Outer boundary of the cell → This is the cell membrane, which controls what enters and exits the cell.
✔ Label: cell membrane

2. Large central structure with a nucleolus inside → This is the nucleus, which contains DNA and controls cell activities.
✔ Label: nucleus

3. Small oval structures scattered in the cytoplasm → These are mitochondria, the powerhouses of the cell that produce energy (ATP).
✔ Label: mitochondrion

4. Jelly-like substance filling the cell → This is the cytoplasm, where organelles are suspended.
✔ Label: cytoplasm

5. Small spherical structures → These are lysosomes, which contain digestive enzymes to break down waste.
✔ Label: lysosome

> 💡 Tip: In animal cells, you might also see the Golgi apparatus or endoplasmic reticulum, but those aren't in the word bank, so we only use the given terms.

🌿 Part 2: Plant Cell (Bottom Diagram)

Word Bank:
- cell wall
- cytoplasm
- mitochondrion
- cell membrane
- nucleus
- chloroplast

Now, let’s label the plant cell:

1. Rigid outer layer surrounding the cell → This is the cell wall, which provides structural support and protection.
✔ Label: cell wall

2. Inner membrane just inside the cell wall → This is the cell membrane, which regulates movement in and out of the cell.
✔ Label: cell membrane

3. Green, oval-shaped structures → These are chloroplasts, where photosynthesis occurs.
✔ Label: chloroplast

4. Large central vacuole → Not in the word bank, so we skip it. But notice: the large empty space is the vacuole, not listed.

5. Central control center → The nucleus, same as in animal cells.
✔ Label: nucleus

6. Jelly-like substance → The cytoplasm, where organelles float.
✔ Label: cytoplasm

7. Small oval structures (similar to mitochondria) → These are mitochondria, for energy production.
✔ Label: mitochondrion

✔ Final Answer Summary:

#### Animal Cell Labels (from top to bottom):
- Top right arrow → cell membrane
- Left arrows (top to bottom) → nucleus, cytoplasm
- Right arrows (top to bottom) → mitochondrion, lysosome

#### Plant Cell Labels (from top to bottom):
- Top right arrow → cell wall
- Middle right arrows (top to bottom) → cell membrane, cytoplasm, mitochondrion
- Left arrows (top to bottom) → chloroplast, nucleus

🧠 Key Differences:

| Feature | Animal Cell | Plant Cell |
|--------|-------------|------------|
| Cell Wall | ✘ No | ✔ Yes |
| Chloroplast | ✘ No | ✔ Yes |
| Large Central Vacuole | ✘ Small or none | ✔ Yes |
| Lysosome | ✔ Present | ⚠️ Sometimes present, but not always emphasized |

✔ Conclusion: Use the word bank to match each structure correctly based on its shape and location. The labels should now be filled in accordingly!
