Which of the following statements are correct regarding the general difference between plant and animal cells?
- Plant cells have cellulose cell walls whilst animal cells do not.
- Plant cells do not have plasma membrane unlike animal cells which do.
- Mature plant cell has one large vacuole whilst animal cell has many small vacuoles.
Select the correct answer using the code given below:
Detailed Explanation:
Answer: Option 3 — 1 and 3 only
This question tests the fundamental structural differences between plant and animal cells. Statement 2 is incorrect because both plant and animal cells possess a plasma membrane, which is a universal feature of all cells.
✅ Statement 1 – Correct: Plant cells have rigid cellulose cell walls for structural support and protection, while animal cells lack cell walls and only have a flexible plasma membrane.
❌ Statement 2 – Incorrect: Both plant and animal cells have plasma membranes (cell membranes); this is a fundamental feature present in all living cells, controlling the movement of substances in and out of the cell.
✅ Statement 3 – Correct: Mature plant cells typically contain one large central vacuole for storage of water, nutrients, and waste, whereas animal cells have multiple small vacuoles that are less prominent.
📝 Short Notes: Plant vs Animal Cells
| Feature | Plant Cell | Animal Cell |
|---|---|---|
| Cell Wall | Present (made of cellulose) | Absent |
| Plasma Membrane | Present | Present |
| Vacuoles | One large central vacuole | Many small vacuoles |
| Chloroplasts | Present (for photosynthesis) | Absent |
| Shape | Fixed, rectangular/polygonal | Variable, usually round/irregular |
| Centrioles | Absent (except lower plants) | Present |
