Step-by-step solution for: Cell Organelles interactive worksheet
Let's solve this step by step.
---
We are asked to label the cell as plant, animal, or bacteria.
Let’s look at key features in the diagram:
- Presence of a nucleus: Yes → This is a eukaryotic cell (not bacteria, which are prokaryotes and lack a nucleus).
- Mitochondria: Present → Eukaryotic cells have mitochondria.
- Centrioles: Present (small structures near the nucleus) → Found in animal cells, not plant cells.
- Large central vacuole: Not present → Plant cells typically have a large central vacuole; this one has small vacuoles.
- Cell wall: Absent → Plant cells have a rigid cell wall (usually made of cellulose), but here the outer boundary is just a cell membrane.
- Chloroplasts: Absent → No green organelles for photosynthesis.
✔ So, based on:
- Presence of nucleus
- Mitochondria
- Centrioles
- Lack of cell wall and chloroplasts
➡️ This is an animal cell.

Now let’s match each labeled structure with the correct term from the list.
Here is the diagram with labels (based on standard biology diagrams):
#### Key Features Identified:
1. Nucleus – Large, round structure with a nucleolus inside (orange circle with a dot).
➤ Label: Nucleus
2. Nuclear envelope / Nuclear membrane – The membrane around the nucleus.
➤ Not listed directly, but the nucleus includes it.
3. Ribosomes – Small dots floating in the cytoplasm or attached to ER.
➤ Label: Ribosome (tiny red dots)
4. Rough Endoplasmic Reticulum (Rough ER) – Network of membranes with ribosomes attached (blue, folded structure).
➤ Label: Rough ER
5. Smooth Endoplasmic Reticulum (Smooth ER) – Network without ribosomes (green, tubular structure).
➤ Label: Smooth ER
6. Golgi Apparatus – Stack of flattened sacs (pink, stacked like pancakes).
➤ Label: Golgi Apparatus
7. Mitochondria – Oval-shaped with inner folds (purple, bean-shaped).
➤ Label: Mitochondria
8. Lysosome – Small, round vesicles (light blue, often smaller than vacuoles).
➤ Label: Lysosome
9. Vacuole – Small, clear sacs (light blue, sometimes larger).
➤ Label: Vacuole
10. Centrioles – Two small cylindrical structures near the nucleus (yellow/orange, short rods).
➤ Label: Centrioles
11. Cytoskeleton – Filaments running through the cytoplasm (thin pink lines).
➤ Label: Cytoskeleton
12. Cytoplasm – The gel-like substance filling the cell (the beige area inside the cell membrane).
➤ Label: Cytoplasm
13. Cell Membrane – Outer boundary of the cell (thick yellow line).
➤ Label: Cell Membrane

#### Type of Cell: Animal Cell
#### Labeling the Diagram:
| Structure | Label |
|---------|-------|
| Large orange circle with dot | Nucleus |
| Blue folded network with dots | Rough ER |
| Green tubular network | Smooth ER |
| Pink stacked sacs | Golgi Apparatus |
| Purple oval with folds | Mitochondria |
| Light blue small sacs | Lysosome |
| Light blue sacs (larger ones) | Vacuole |
| Yellow/orange rod-like structures near nucleus | Centrioles |
| Thin pink lines throughout | Cytoskeleton |
| Beige area inside membrane | Cytoplasm |
| Outer yellow border | Cell Membrane |
| Tiny red dots on ER and free-floating | Ribosome |

- This is an animal cell because it has centrioles, no cell wall, no chloroplasts, and no large central vacuole.
- All organelles are correctly matched using standard biological knowledge.
