Animal Cell Worksheet - Fill the Worksheet and Color by Number PDF

You’re working on an “Animal Cell – Fill the Worksheet and Color by Number” activity. The goal is to:

1. Identify each numbered organelle in the black-and-white diagram.
2. Match it to the correct color using the color code table.
3. Fill in the missing information (organelle name, structure/function) in the worksheet.
4. Color the diagram according to the color code.

🔍 STEP 1: Identify Organelles by Number (from the black-and-white diagram)

Here’s what each number typically refers to in a standard animal cell diagram like this one:

| No. | Organelle Name |
|-----|-----------------------------|
| 1 | Nucleus |
| 2 | Nuclear Envelope / Membrane |
| 3 | Rough Endoplasmic Reticulum |
| 4 | Golgi Apparatus (Golgi Body)|
| 5 | Mitochondrion |
| 6 | Lysosome |
| 7 | Centrioles |
| 8 | Ribosomes |
| 9 | Plasma (Cell) Membrane |

> 📌 *Note: Some diagrams may vary slightly — for example, “Smooth ER” might be shown instead of “Rough ER,” or ribosomes might not be numbered separately. But based on standard educational diagrams and your color-coded table, this is the most likely match.*

🎨 STEP 2: Match Colors to Organelles (Based on Your Table)

Your worksheet shows:

| No. | Color | Organelle Name | Structure/Function/Occurrence |
|-----|-------------|--------------------------|---------------------------------------------------------------|
| 1 | Dark Green | Nucleus | It is also called the “Brain of the Cell”. |
| 2 | Orange | Endoplasmic reticulum | It provides internal support / framework to the cell. |
| 3 | Pink | Golgi Body | It produces, sorts, and ships proteins. |
| 4 | Red | Lysosome | Contains digestive enzymes to break down waste. |
| 5 | Light Blue | Mitochondrion | Produces energy (ATP) — “Powerhouse of the Cell”. |
| 6 | ??? | *(Not visible in image)*| *(To be filled)* |

> ⚠️ Note: There appears to be a mismatch in your table:
> - “Endoplasmic reticulum” is listed under #2 (Orange), but its function says “provides internal support/framework” — that actually describes the cytoskeleton, not the ER.
> - The Golgi Body (#3, Pink) — function is correctly described as processing/shipping proteins.
> - You need to fill in #6 — likely Centrioles or Ribosomes or Plasma Membrane.

Let’s fix and complete the table accurately:

✔ CORRECTED & COMPLETED WORKSHEET TABLE

| No. | Color | Organelle Name | Structure / Function / Occurrence |
|-----|-------------|--------------------------|--------------------------------------------------------------------------------------------------|
| 1 | Dark Green | Nucleus | Controls cell activities; contains DNA. Called the “Brain of the Cell”. |
| 2 | Orange | Endoplasmic Reticulum | Synthesizes proteins (rough ER) and lipids (smooth ER); transport system inside the cell. |
| 3 | Pink | Golgi Apparatus | Modifies, sorts, and packages proteins for secretion or delivery within the cell. |
| 4 | Red | Lysosome | Contains hydrolytic enzymes to digest macromolecules, old organelles, and pathogens. |
| 5 | Light Blue | Mitochondrion | Produces ATP via cellular respiration — “Powerhouse of the Cell”. |
| 6 | Yellow | Plasma Membrane | Selectively permeable barrier; controls what enters/exits the cell. |
| 7 | Purple | Centrioles | Organize microtubules during cell division (found near nucleus in animal cells). |
| 8 | Brown | Ribosomes | Sites of protein synthesis; found free in cytoplasm or attached to rough ER. |
| 9 | Gray | Cytoskeleton | Provides structural support, shape, and enables cell movement. |

> 💡 *If your original worksheet only has 6 rows, you may only need to fill up to #6. But since the diagram has 9 numbers, we’ve included all for completeness.*

🖍️ STEP 3: COLOR THE DIAGRAM

Use the above color codes to color your black-and-white diagram:

- #1 Nucleus → Dark Green
- #2 ER → Orange
- #3 Golgi → Pink
- #4 Lysosome → Red
- #5 Mitochondrion → Light Blue
- #6 Plasma Membrane → Yellow *(if included)*
- #7 Centrioles → Purple
- #8 Ribosomes → Brown *(tiny dots — may be hard to color individually)*
- #9 Cytoskeleton → Gray *(filamentous network — may be lightly shaded)*

🧬 EXTRA TIP: Key Functions Summary

- Nucleus: Control center → DNA storage.
- ER: Protein/lipid factory.
- Golgi: Post office → modifies & ships proteins.
- Lysosome: Recycling center → breaks down waste.
- Mitochondria: Power plant → makes ATP.
- Plasma Membrane: Gatekeeper → regulates traffic.
- Centrioles: Cell division organizers.
- Ribosomes: Protein builders.
- Cytoskeleton: Structural scaffold + mobility.
