Which of the following statements are correct regarding the general difference between plant and animal cells?
1. Plant cells have cellulose cell walls whilst animal cells do not.
2. Plant cells do not have plasma membrane unlike animal cells which do.
3. Mature plant cell has one large vacuole whilst animal cell has many small vacuoles.
Select the correct answer using the code given below:
(a) 1 and 2 only · (b) 2 and 3 only · (c) 1 and 3 only · (d) 1, 2 and 3
उत्तर और व्याख्या · explanation in English
Answer: (c) केवल 1 और 3
A plant cell has a cellulose cell wall and, when mature, usually one large central vacuole, while an animal cell has no cell wall and only small vacuoles, if any. Statement 2 is wrong because every cell, plant or animal, is enclosed by a plasma membrane.
- ✓ 1. The plant cell wall is made mainly of cellulose. Animal cells lack a rigid cell wall, which lets them change shape easily.
- ✗ 2. The plasma membrane (cell membrane) is the universal boundary of a cell. Plant cells have it too, just inside the cell wall.
- ✓ 3. A mature plant cell usually has one large central vacuole filled with cell sap. Animal cells may have vacuoles, but they are not as large.
Remember · Cell wall (cellulose) and one big central vacuole belong to plant cells. The plasma membrane is present in all cells.
