Educational worksheet comparing eukaryotes and prokaryotes with interactive exercises on cell theory.

Let's solve this worksheet step by step.

Part 1: Eukaryote vs. Prokaryote

For each statement, write:
- P = prokaryotes only
- E = eukaryotes only
- both = applies to both

---

1. I have a cell membrane (plasma membrane)
✔ Both – All cells, whether prokaryotic or eukaryotic, have a plasma membrane.

2. I have a nucleus
✔ E – Only eukaryotes have a nucleus. Prokaryotes do not.

3. Bacteria are an example of me
✔ P – Bacteria are prokaryotes.

4. Fungi are an example of me
✔ E – Fungi are eukaryotes.

5. Animals are an example of me
✔ E – Animals are multicellular eukaryotes.

6. I contain ribosomes
✔ Both – Both prokaryotes and eukaryotes have ribosomes (though they differ in size).

7. I contain membrane-bound organelles
✔ E – Only eukaryotes have membrane-bound organelles like mitochondria, nucleus, etc.

8. I contain cytoplasm
✔ Both – All cells have cytoplasm (the gel-like substance inside the cell).

9. Your body cells are made of this type of cell
✔ E – Human body cells are eukaryotic.

10. Protists are an example of me
✔ E – Protists are eukaryotes.

11. Plants are an example of me
✔ E – Plants are eukaryotes.

12. I contain genetic material such as DNA
✔ Both – All cells contain DNA as genetic material.

Words to choose from:
Cell, smallest, unit, living things, pre-existing

---

1. The _________ is the ____________ living ___________ in all organisms.
→ The cell is the smallest living unit in all organisms.

✔️ Final: The cell is the smallest living unit in all organisms.

2. All _______________ are made of cells.
→ All living things are made of cells.

✔️ Final: All living things are made of cells.

3. All cells come from other ____________________ cells.
→ All cells come from other pre-existing cells.

✔️ Final: All cells come from other pre-existing cells.

✔ Answers for Part 2:

1. The cell is the smallest living unit in all organisms.
2. All living things are made of cells.
3. All cells come from other pre-existing cells.

🔍 Summary of Key Concepts:

- Prokaryotes (e.g., bacteria): No nucleus, no membrane-bound organelles, simpler structure.
- Eukaryotes (e.g., animals, plants, fungi, protists): Have nucleus and membrane-bound organelles.
- Cell Theory:
1. The cell is the basic unit of structure and function in living things.
2. All living things are composed of cells.
3. All cells arise from pre-existing cells.
