Cell Organelles activity - 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.

Top Diagram: Animal Cell

This is an animal cell. It has typical organelles but lacks a cell wall, chloroplasts, and a large central vacuole (which are present in plant cells).

We are given the following list to label:

1. Nucleus
2. Nucleolus
3. Cytoplasm
4. Cell membrane
5. Lysosome
6. Endoplasmic Reticulum
7. Golgi Apparatus
8. Mitochondria
9. Ribosome

Now, let’s match each structure with its correct label:

#### Labeling the Animal Cell:

- Top center (pink structure): This is the Nucleus → Label 1
- Inside the nucleus, the small yellow circle is the Nucleolus → Label 2
- Blue outer layer: The Cell membrane → Label 4
- Green stacked structures (like pancakes): These are the Endoplasmic Reticulum (ER) → Label 6
- The rough ER has ribosomes on it; smooth ER does not.
- Orange folded structure: This is the Golgi Apparatus → Label 7
- Pink bean-shaped structures: These are Mitochondria → Label 8
- Small yellow spheres: These are Lysosomes → Label 5
- Tiny dots on the green structures: These are Ribosomes → Label 9
- Blue gel-like area surrounding organelles: This is the Cytoplasm → Label 3

Now, place these labels in the correct boxes around the diagram:

> From top to bottom, left to right:

1. Top-left box (pointing to nucleus): 1. Nucleus
2. Top-right box (pointing to nucleolus): 2. Nucleolus
3. Middle-right box (pointing to cell membrane): 4. Cell membrane
4. Right side, pointing to lysosome: 5. Lysosome
5. Right side, pointing to endoplasmic reticulum: 6. Endoplasmic Reticulum
6. Bottom-right box (pointing to mitochondria): 8. Mitochondria
7. Bottom-center box (pointing to Golgi apparatus): 7. Golgi Apparatus
8. Left side, pointing to ribosome: 9. Ribosome
9. Left side, pointing to cytoplasm: 3. Cytoplasm

Bottom Diagram: Plant Cell

This is a plant cell. It has all the organelles of an animal cell plus:
- Cell wall
- Chloroplasts
- Large central vacuole

Given list for labeling:

1. Ribosome
2. Cytoplasm
3. Golgi Apparatus
4. Mitochondria
5. Chloroplasts
6. Endoplasmic Reticulum
7. Vacuole
8. Nucleus

Note: The cell wall is not listed, so we won't label it.

Now, identify each part:

- Outermost green rigid layer: This is the Cell wall, but it's not in the list → skip
- Green oval structures with green dots inside: These are Chloroplasts → Label 5
- Large purple structure in the center: This is the Vacuole → Label 7
- Blue bean-shaped structures: These are Mitochondria → Label 4
- Stacked pink structure: This is the Golgi Apparatus → Label 3
- Network of membranes (light orange): This is the Endoplasmic Reticulum → Label 6
- Pink circular structure with a dot inside: This is the Nucleus → Label 8
- Tiny dots on the ER: These are Ribosomes → Label 1
- Yellow gel-like area: This is the Cytoplasm → Label 2

Now, assign labels to the boxes:

> From top to bottom, left to right:

1. Top-left box (pointing to nucleus): 8. Nucleus
2. Top-right box (pointing to chloroplast): 5. Chloroplasts
3. Right side, pointing to cell membrane or cytoplasm? Actually, the cytoplasm is the fluid — likely the box pointing to the yellow area → 2. Cytoplasm
4. Right side, pointing to mitochondria: 4. Mitochondria
5. Right side, pointing to endoplasmic reticulum: 6. Endoplasmic Reticulum
6. Bottom-right box (pointing to Golgi apparatus): 3. Golgi Apparatus
7. Bottom-center box (pointing to vacuole): 7. Vacuole
8. Left side, pointing to ribosome: 1. Ribosome
9. Left side, pointing to chloroplast: Already labeled above — if another one, also 5. Chloroplasts

Wait — there are two chloroplasts shown. So two boxes may point to chloroplasts.

But let’s go carefully.

Looking at the diagram:

- Top-left box: Points to nucleus → 8. Nucleus
- Top-right box: Points to a chloroplast → 5. Chloroplasts
- Middle-right box: Points to cytoplasm → 2. Cytoplasm
- Next down: Points to mitochondria → 4. Mitochondria
- Next down: Points to ER → 6. Endoplasmic Reticulum
- Bottom-right box: Points to Golgi → 3. Golgi Apparatus
- Bottom-center box: Points to vacuole → 7. Vacuole
- Left side, top box: Points to ribosome → 1. Ribosome
- Left side, bottom box: Points to chloroplast → 5. Chloroplasts

So the final labeling is:
