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:
D.1, 2 and 3
B.2 and 3 only
C.1 and 3 only
A.1 and 2 only
Correct Answer: Option C
The key distinction between plant and animal cells lies in the presence of a cell wall in plant cells, which provides mechanical support. Animal cells lack this cell wall.
Plant cells possess both a cell wall (made of cellulose) and a plasma membrane, contrary to statement 2.
Mature plant cells typically feature a large central vacuole, potentially occupying up to 90% of the cell's volume. Animal cells, in contrast, contain many small vacuoles.
Statement 1 is correct. Statement 2 is not correct. Statement 3 is correct.
Hence, only statements 1 and 3 are correct.
