Educational worksheet showing labeled diagrams of animal and plant cells for learning cell biology.

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 flexible cell membrane and various organelles.

List of structures (from the right-hand box):
1. Nucleus
2. Nucleolus
3. Cytoplasm
4. Cell membrane
5. Lysosome
6. Endoplasmic Reticulum
7. Golgi Apparatus
8. Mitochondria
9. Ribosome

Now, match each label to the correct structure in the diagram:

- Nucleus: The large pink structure in the center with a yellow dot inside.
- ✔ Label the large pink structure → 1. Nucleus

- Nucleolus: The small yellow circle inside the nucleus.
- ✔ Inside the nucleus → 2. Nucleolus

- Cytoplasm: The blue jelly-like substance surrounding the organelles.
- ✔ The blue area around all organelles → 3. Cytoplasm

- Cell membrane: The outer boundary of the cell (thin line).
- ✔ Outer edge of the cell → 4. Cell membrane

- Lysosome: Small yellow spheres (often shown as tiny dots or circles).
- ✔ Small yellow round structures → 5. Lysosome

- Endoplasmic Reticulum (ER): Green network of membranes; rough ER has ribosomes attached.
- ✔ Green stacked structures → 6. Endoplasmic Reticulum

- Golgi Apparatus: Orange stack of flattened sacs (looks like a stack of pancakes).
- ✔ Orange structure near the nucleus → 7. Golgi Apparatus

- Mitochondria: Pink oval-shaped structures with folds (cristae) inside.
- ✔ Pink oval shapes with inner folds → 8. Mitochondria

- Ribosome: Tiny black dots on the ER or free in cytoplasm.
- ✔ Tiny dots on green ER or floating → 9. Ribosome

Bottom Diagram: Plant Cell

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

List of structures (from the right-hand box):
1. Ribosome
2. Cytoplasm
3. Golgi Apparatus
4. Mitochondria
5. Chloroplasts
6. Endoplasmic Reticulum
7. Vacuole
8. Nucleus

Now, label accordingly:

- Ribosome: Tiny black dots (often on ER or free).
- ✔ Tiny dots on ER or scattered → 1. Ribosome

- Cytoplasm: Yellowish area between organelles.
- ✔ Yellow background → 2. Cytoplasm

- Golgi Apparatus: Pink stack of sacs.
- ✔ Pink layered structure → 3. Golgi Apparatus

- Mitochondria: Blue oval structures with inner folds.
- ✔ Blue ovals → 4. Mitochondria

- Chloroplasts: Green oval structures with internal stacks (grana).
- ✔ Green oval bodies → 5. Chloroplasts

- Endoplasmic Reticulum: Network of tubules (orange/pink lines).
- ✔ Orange network near nucleus → 6. Endoplasmic Reticulum

- Vacuole: Large purple central structure.
- ✔ Large central purple bubble → 7. Vacuole

- Nucleus: Purple oval structure with nucleolus inside.
- ✔ Purple oval near center → 8. Nucleus

#### Animal Cell (Top Diagram):
From top to bottom, left to right (based on lines):

1. Nucleus → Top center (pink)
2. Nucleolus → Inside nucleus (yellow dot)
3. Cytoplasm → Blue background
4. Cell membrane → Outer edge
5. Lysosome → Small yellow spheres
6. Endoplasmic Reticulum → Green network
7. Golgi Apparatus → Orange stack
8. Mitochondria → Pink folded ovals
9. Ribosome → Tiny black dots

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

🔍 Summary of Key Differences:

| Feature | Animal Cell | Plant Cell |
|----------------------|----------------------------|----------------------------------|
| Cell Wall | ✘ No | ✔ Yes (rigid outer layer) |
| Chloroplasts | ✘ No | ✔ Yes (for photosynthesis) |
| Large Central Vacuole| ✘ No | ✔ Yes (stores water/nutrients) |
| Shape | Irregular/flexible | Rectangular/regular |
| Lysosomes | ✔ Present | ⚠️ Often present but less common |
