(b) Cell membrane
(c) Plasma wall
(d) Cell wall

Answer 1

(d) Cell wall

Step-by-step explanation:

The cell wall is a structure located on the outside of the cell membrane in the cells of plants, bacteria, fungi, and algae. It is a resistant, tough and flexible layer, which has the vital function of supporting the osmotic pressure inside the cell, preventing the cell from lysis when water enters. Besides, it has the function of giving rigidity, support and defining the shape of the cell.
