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.

🔹 Top Diagram: Animal Cell

Word Bank (Animal Cell):
- cytoplasm
- mitochondrion
- cell membrane
- nucleus
- lysosome

Now, let’s analyze the animal cell diagram:

1. Outermost layer (blue arrow pointing to the outer boundary)
→ This is the cell membrane – it controls what enters and exits the cell.

2. Large central structure with a dark dot inside (blue arrow pointing to it)
→ This is the nucleus – it contains DNA and controls cell activities.

3. Small oval structures scattered throughout the cell (blue arrow pointing to one)
→ These are mitochondria – they produce energy (ATP) for the cell.

4. The jelly-like substance filling the cell (blue arrow pointing to the area around organelles)
→ This is the cytoplasm – it holds all the organelles in place.

5. Small round structures near the nucleus or scattered (blue arrow pointing to one)
→ These are lysosomes – they digest waste materials and cellular debris.

✔ So, the labels for the animal cell from left to right and top to bottom:
- Top right: cell membrane
- Middle right: mitochondrion
- Bottom right: lysosome
- Left side (top): nucleus
- Left side (bottom): cytoplasm

> 💡 Note: The arrows point to these parts accordingly.

🔹 Bottom Diagram: Plant Cell

Word Bank (Plant Cell):
- cell wall
- cytoplasm
- mitochondrion
- cell membrane
- chloroplast
- nucleus

Now, analyze the plant cell diagram:

1. Rigid outer layer (black arrow pointing to the thick outer boundary)
→ This is the cell wall – provides structural support and protection.

2. Just inside the cell wall (black arrow pointing to the inner thin layer)
→ This is the cell membrane – lies beneath the cell wall and regulates movement.

3. Green oval structures (black arrow pointing to them)
→ These are chloroplasts – they perform photosynthesis (only in plant cells).

4. Large central vacuole (black arrow pointing to the big empty space)
→ Although not in the word bank, it's implied that the large space is the vacuole, but since it's not listed, we focus on labeled ones.

5. Small oval structures (black arrow pointing to one)
→ These are mitochondria – same as in animal cells, produce energy.

6. Central structure with a dark dot (black arrow pointing to it)
→ This is the nucleus – controls cell functions.

7. Jelly-like substance surrounding organelles (black arrow pointing to the area)
→ This is the cytoplasm – holds all the organelles.

✔ So, the labels for the plant cell from left to right and top to bottom:
- Right side (top): cell wall
- Right side (middle): cell membrane
- Right side (bottom): chloroplast
- Left side (top): mitochondrion
- Left side (bottom): nucleus
- Middle (bottom): cytoplasm

> 🌿 Note: The chloroplasts are green and usually located in the cytoplasm; the large central vacuole is not labeled in the word bank, so we don't need to label it here.

✔ Final Answer:

#### Animal Cell Labels (from arrows):
- Top right: cell membrane
- Middle right: mitochondrion
- Bottom right: lysosome
- Left (top): nucleus
- Left (bottom): cytoplasm

#### Plant Cell Labels (from arrows):
- Right (top): cell wall
- Right (middle): cell membrane
- Right (bottom): chloroplast
- Left (top): mitochondrion
- Left (bottom): nucleus
- Middle (bottom): cytoplasm

📝 Summary:

This worksheet helps students distinguish between animal and plant cells by labeling their key organelles. The main differences are:
- Plant cells have a cell wall, chloroplasts, and a large central vacuole.
- Animal cells lack these and have lysosomes instead.
