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:

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.
