Statement A : Cell wall forms an outer covering for the plasma membrane of fungi and animals. Statement B : The cell wall of a young plant cell, which is capable of growth is called secondary wall.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Cell wall forms an outer covering for the plasma membrane of fungi only. In animal cell wall is absent. The cell wall of a young plant cell, which is capable of growth is called primary wall.
