Answer 2

Cell Wall

• A cell wall is a physical layer that surrounds some cell types and extends slightly beyond the cell membrane.
• It has the ability to be hard, elastic, as well as rigid at times. It works as a filtration mechanism as well as support and protection for the cell.
• The cell wall of plant cells covers the plasma membrane & offers structural stress as well as resistance to mechanical as well as osmotic stress.
• It also enables cells to create turgor pressure or the pressure of cell contents against the cell wall.
