Parts of animal and plant cell worksheet - 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 and lists.

Top Diagram: Animal Cell

The top image is an animal cell, which lacks a cell wall, chloroplasts, and a large central vacuole (common in plant cells). The labeled parts are:

#### List of Organelles (Right Side):
1. Nucleus
2. Nucleolus
3. Cytoplasm
4. Cell membrane
5. Lysosome
6. Endoplasmic Reticulum
7. Golgi Apparatus
8. Mitochondria
9. Ribosome

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

- Nucleus – Large pink structure with a yellow dot inside (nucleolus) — top center
- Nucleolus – Small yellow sphere inside the nucleus — inside the nucleus
- Cytoplasm – Blue area surrounding organelles — entire inner region outside nucleus
- Cell membrane – Outer boundary of the cell — outer blue line
- Lysosome – Small yellow spheres (often shown as dots) — scattered in cytoplasm
- Endoplasmic Reticulum (ER) – Green network (rough ER has ribosomes; smooth ER does not) — green folded structures
- Golgi Apparatus – Orange stacked sacs — orange structure near nucleus
- Mitochondria – Pink oval structures with folds (cristae) — pink ovals with internal lines
- Ribosome – Tiny dots on rough ER or free in cytoplasm — small black dots on green ER

Bottom Diagram: Plant Cell

This is a plant cell, which includes features like a cell wall, chloroplasts, and a large central vacuole.

#### List of Organelles (Right Side):
1. Ribosome
2. Cytoplasm
3. Golgi Apparatus
4. Mitochondria
5. Chloroplasts
6. Endoplasmic Reticulum
7. Vacuole
8. Nucleus

Now, label the parts:

- Nucleus – Purple structure with a small dot inside — center-left
- Vacuole – Large purple central structure — big central bubble
- Chloroplasts – Green oval structures with internal stacks — green ovals scattered
- Mitochondria – Blue oval structures — blue ovals with folds
- Endoplasmic Reticulum (ER) – Network of membranes (pinkish) — pink folded structure near nucleus
- Golgi Apparatus – Stack of flattened sacs (purple/pink) — stacked pink structure near nucleus
- Cytoplasm – Yellow area surrounding organelles — yellow background
- Ribosome – Tiny dots on ER or free — small dots on ER
- Cell wall – Outer green rigid layer — outermost green border *(Note: Not in list but visible)*

✔ Final Labeling Guide:

#### Top (Animal Cell):

From the diagram:
- Top left: Cytoplasm
- Top right: Cell membrane
- Center top: Nucleus
- Inside nucleus: Nucleolus
- Green folded structure: Endoplasmic Reticulum
- Orange stack: Golgi Apparatus
- Pink ovals with folds: Mitochondria
- Yellow spheres: Lysosome
- Small dots on green ER: Ribosome
- Blue outer layer: Cell membrane (already labeled)
- Blue area around organelles: Cytoplasm

#### Bottom (Plant Cell):

- Top left: Cell wall *(not listed but present)*
- Top right: Chloroplasts
- Middle: Nucleus
- Large central purple: Vacuole
- Green ovals: Chloroplasts
- Blue ovals: Mitochondria
- Pink folded structure: Endoplasmic Reticulum
- Stacked pink sacs: Golgi Apparatus
- Yellow area: Cytoplasm
- Tiny dots: Ribosome

🧠 Key Differences Between Plant and Animal Cells:

| Feature | Plant Cell | Animal Cell |
|----------------------|--------------------------|-------------------------|
| Cell Wall | Yes (rigid, cellulose) | No |
| Chloroplasts | Yes (for photosynthesis) | No |
| Central Vacuole | Yes (large) | Small or absent |
| Shape | Fixed (rectangular) | Irregular (round) |
| Lysosomes | Rare | Present |
