BACTERIAL CELL online exercise for - Free Printable

Let’s solve this step by step.

We are given a diagram of a bacterial cell with labels pointing to different parts. The task is to match each label (like “PILI”, “CYTOPLASM”, etc.) to the correct part in the diagram.

But wait — looking at the image, we can see that all the labels are already placed next to their corresponding structures, and lines connect them to the right spots. So actually, this isn’t a matching exercise where you have to draw lines — it’s more like identifying which structure is which based on the labeled diagram.

However, since the user didn’t ask a specific question (like “What does the nucleoid do?” or “Which part helps the bacterium move?”), and just said “Solve the problem accurately,” I think the goal here is to correctly identify each labeled part as shown in the diagram — meaning, confirm that the labels are correctly assigned.

Let’s go through each label one by one and verify if it points to the right structure:

1. PILI – These are short, hair-like projections on the surface. In the diagram, green stubby things sticking out all over → yes, that’s pili. ✔️

2. CYTOPLASM – This is the jelly-like stuff inside the cell membrane. The blue area filling most of the inside → yes, cytoplasm. ✔️

3. CELL WALL – The thick red layer outside the plasma membrane → yes, that’s the cell wall. ✔️

4. CAPSULE – The outermost yellow/greenish slimy layer → yes, capsule is outside the cell wall. ✔️

5. FLAGELLUM – The long whip-like tail used for movement → the big green curly thing at the end → yes, flagellum. ✔️

6. NUCLEOID – The tangled mass of DNA in the center (not enclosed in a nucleus) → the dark red squiggly blob → yes, nucleoid. ✔️

7. PLASMID – Small circular DNA pieces floating in cytoplasm → small red circles inside → yes, plasmids. ✔️

8. PLASMA MEMBRANE – The thin line just inside the cell wall → the inner boundary of the red cell wall → yes, plasma membrane. ✔️

9. RIBOSOMES – Tiny dots scattered in cytoplasm → the little blue dots → yes, ribosomes. ✔️

✔ All labels are correctly matched to their structures in the diagram.

So, if the “problem” was to check whether the labeling is correct — then the answer is: Yes, all labels are correctly placed.

If the problem was to name each part — then we’ve done that above.

Since no specific question was asked beyond “solve the problem,” and the diagram is fully labeled, the best interpretation is that the student needs to understand what each part is — so we’ll summarize the function of each briefly to help learning.

Final Answer:
All labeled parts in the bacterial cell diagram are correctly identified:
- PILI = short surface hairs
- CYTOPLASM = internal fluid
- CELL WALL = rigid outer layer
- CAPSULE = slippery outer coating
- FLAGELLUM = long moving tail
- NUCLEOID = main DNA region
- PLASMID = extra small DNA rings
- PLASMA MEMBRANE = inner boundary layer
- RIBOSOMES = protein-making dots

Each label matches its correct structure in the image.
