It looks like you've uploaded an image of a
"CELLS alive! - Bacterial Cell Worksheet", which is a diagram of a bacterial cell with labeled parts and a set of questions or fill-in-the-blank tasks. However, since I can't view images directly, I cannot see the specific details of your worksheet.
But based on the description and typical content of such worksheets, here's how I can help:
---
🔍 Likely Task:
The worksheet probably asks you to:
- Label the parts of the bacterial cell.
- Match structures with their functions.
- Answer questions about prokaryotic cells (like bacteria).

🧬 Common Structures in a Bacterial Cell (as shown in the diagram):
Here’s a breakdown of the typical labeled parts in a bacterial cell diagram like this:
| Structure | Function |
|---------|--------|
|
1. Nucleoid | Region where DNA is located (not enclosed in a nucleus) |
|
2. Ribosome | Site of protein synthesis |
|
3. Flagella | Long whip-like structures for movement |
|
4. Pili | Hair-like appendages; used for attachment or DNA transfer |
|
5. Cell Wall | Provides shape and protection; made of peptidoglycan |
|
6. Plasma Membrane | Controls passage of substances in and out of cell |
|
7. Capsule | Protective outer layer; helps in adhesion and evading immune system |
|
8. Cytoplasm | Gel-like substance inside the cell where metabolic reactions occur |
|
9. Plasmid | Small circular DNA molecule; often carries antibiotic resistance genes |

✔ How to Solve the Worksheet:
1.
Label the Diagram: Use the numbers or letters provided to match each structure with its correct name.
2.
Answer Questions: Typical questions might be:
- What is the function of the capsule?
→ *Protects the cell from phagocytosis and helps in attachment.*
- Why don’t bacteria have a nucleus?
→ *Because they are prokaryotes; their DNA is located in the nucleoid without a membrane.*
- What is the role of flagella?
→ *Motility – allows the bacterium to move.*
---
💡 Tips:
- Remember: Bacteria are
prokaryotes → no nucleus, no membrane-bound organelles.
- The
nucleoid is not surrounded by a membrane — that’s key.
-
Plasmids are extra-chromosomal DNA — important in genetic engineering and antibiotic resistance.

If you can describe the specific questions or blanks in the worksheet (e.g., “What structure helps the bacterium move?”), I can give you the exact answers.
Alternatively, if you type out the text of the worksheet or describe what’s missing, I’ll solve it step-by-step!
