Red blood cells provide oxygen from the lungs to the various tissues in the body, and in so doing return CO2 to the lungs to be breathed out. They don't serve an immunological function.
Cell protection and antioxidants.
protection
it depends on if its a plant or an animal cell if its an plant cell its the second layer of protection and in a animal cell its the main protection
The cell wall, which is found in plant cells, gives the cell its shape and provides protection not found in animal cells. The cell wall is made of cellulose and provides structural support and protection for the plant cell.

For the protection
The cell membrane in animal cells and the cell wall in plant cells give the cell its form, shape, and protection.
The viscous layer that provides protection and lubrication for the cell membrane is known as the glycocalyx. It is composed of glycoproteins and polysaccharides that help in cell-cell recognition and protection against pathogens.
The cell wall is the protection or barrier around the cell to maintain the cell's shape.
