Plant cells have a cell wall surrounding the protoplasm.

In 1665 Robert Hooke discovered cell wall as the first cell structure.

The non-living rigid structure called the cell wall forms an outer covering for the plasma membrane of fungi and plants.

The cell wall gives shape, support and rigidity to the cell, protects cell from mechanical damage and infection, helps in cell-to-cell interaction, provides barrier to undesirable macromolecules

The main structural component of cell walls is cellulose.
