The Animal Cell worksheet showing labeled organelles and a table for learning cell structure.

Let’s solve this step by step.

We are looking at a diagram of an animal cell with numbered labels (1 through 10) pointing to different parts inside the cell. Below the diagram, there is a table with three columns: “Organelle,” “What it looks like,” and “Function.” We need to fill in that table using what we know about animal cells.

First, let’s identify each labeled part based on standard animal cell structure:

Label 1 → Points to the outer boundary of the cell → This is the Cell Membrane
Label 2 → Points to small dots scattered in the cytoplasm → These are Ribosomes
Label 3 → Points to bean-shaped structures with inner folds → These are Mitochondria
Label 4 → Points to the large central round structure → This is the Nucleus
Label 5 → Points to the gel-like substance filling the cell → This is the Cytoplasm
Label 6 → Points to stacked flattened sacs near the nucleus → This is the Golgi Apparatus
Label 7 → Points to network of tubes near the nucleus → This is the Endoplasmic Reticulum (ER) — likely rough ER since ribosomes may be attached
Label 8 → Points to small circular sacs → These could be Vesicles or Lysosomes — in many diagrams, label 8 points to lysosomes
Label 9 → Points to another mitochondrion (same as label 3) → So also Mitochondria
Label 10 → Points to the nucleolus inside the nucleus → This is the Nucleolus

Wait — let’s double-check common labeling conventions for animal cell diagrams:

Typical labels:
- Cell membrane = outer edge
- Cytoplasm = jelly inside
- Nucleus = big circle in center
- Nucleolus = smaller circle inside nucleus
- Mitochondria = oval with squiggles inside
- Ribosomes = tiny dots
- Golgi = stack of pancakes
- ER = maze-like lines around nucleus
- Lysosome = small circle (sometimes shown with enzymes inside)
- Vesicle = small sac (may look similar to lysosome)

In many school diagrams:
→ Label 8 often points to lysosome
→ Label 9 might point to another organelle — but here it looks like another mitochondrion? Wait, no — looking again, label 9 points to a structure that looks like a centriole? But centrioles are usually paired and near the nucleus. Actually, in some diagrams, label 9 points to the centrosome or centrioles.

But wait — let’s re-express based on most common textbook labeling for this exact type of diagram (since this is a standard worksheet):

Actually, after checking common versions of this worksheet online (as this is a known template), the correct matching is:

1 – Cell Membrane
2 – Ribosome
3 – Mitochondria
4 – Nucleus
5 – Cytoplasm
6 – Golgi Body/Apparatus
7 – Endoplasmic Reticulum (Rough)
8 – Lysosome
9 – Centriole (or sometimes Vacuole — but in animal cells, vacuoles are small; centrioles are more commonly labeled here)
10 – Nucleolus

BUT — in many basic middle/high school diagrams, they simplify and don’t include centrioles. Let’s think again.

Looking at the shape:

Label 9 → It’s a pair of cylindrical structures perpendicular to each other → That’s definitely Centrioles

Label 8 → Small circle → Could be lysosome or vesicle → In animal cell diagrams, often labeled as Lysosome

Label 10 → Inside nucleus → Nucleolus

So now, let’s build the table.

We’ll list each organelle, describe its appearance simply, and state its function in simple terms.

Step-by-step filling:

1. Cell Membrane
- What it looks like: Thin outer layer surrounding the whole cell
- Function: Controls what enters and leaves the cell

2. Ribosome
- What it looks like: Tiny dots floating in cytoplasm or stuck on ER
- Function: Makes proteins

3. Mitochondria
- What it looks like: Bean-shaped with wavy lines inside
- Function: Produces energy (ATP) for the cell — “powerhouse”

4. Nucleus
- What it looks like: Large round structure in center, contains DNA
- Function: Controls cell activities and stores genetic info

5. Cytoplasm
- What it looks like: Jelly-like fluid filling the cell
- Function: Holds organelles in place and where many chemical reactions happen

6. Golgi Apparatus
- What it looks like: Stack of curved flat sacs
- Function: Packages and ships proteins made by ribosomes

7. Endoplasmic Reticulum (ER)
- What it looks like: Network of folded membranes/tubes near nucleus
- Function: Transports materials; rough ER has ribosomes and helps make proteins

8. Lysosome
- What it looks like: Small round sac
- Function: Breaks down waste and old cell parts — “clean-up crew”

9. Centriole
- What it looks like: Two short cylinders at right angles
- Function: Helps cell divide during mitosis

10. Nucleolus
- What it looks like: Dark spot inside the nucleus
- Function: Makes ribosomes

Now, note: Some worksheets combine or simplify. For example, sometimes “Endoplasmic Reticulum” is just called “ER”, and “Golgi Apparatus” is called “Golgi Body”.

Also, in some versions, label 9 might be misidentified — but given the drawing shows two perpendicular cylinders, it’s centrioles.

However — if this is for a younger grade level, they might not teach centrioles. But since it’s labeled, we should include it.

Alternatively, in some diagrams, label 9 points to a vacuole — but animal cells have small vacuoles, and the shape doesn’t match. The drawing clearly shows centrioles.

Final decision: Use standard biological identification.

Now, write the table entries clearly.

Final Answer:

| Organelle | What it looks like | Function |
|-----------------------|---------------------------------------------|-----------------------------------------------|
| Cell Membrane | Thin outer layer | Controls what goes in/out of cell |
| Ribosome | Tiny dots | Makes proteins |
| Mitochondria | Bean-shaped with inner folds | Makes energy (ATP) for the cell |
| Nucleus | Large round structure in center | Controls cell; holds DNA |
| Cytoplasm | Jelly-like fluid | Holds organelles; site of many reactions |
| Golgi Apparatus | Stack of flattened sacs | Packages and ships proteins |
| Endoplasmic Reticulum | Maze-like tubes near nucleus | Transports materials; makes proteins (rough) |
| Lysosome | Small round sac | Breaks down waste and germs |
| Centriole | Two short cylinders at right angles | Helps cell divide |
| Nucleolus | Dark spot inside nucleus | Makes ribosomes |

Note: If your teacher uses simplified terms, you can write “Golgi Body” instead of “Golgi Apparatus”, and “ER” instead of “Endoplasmic Reticulum”. Also, some classes skip centrioles — but since it’s labeled, include it.
