"It prevents harmful substances from entering a cell."
The cell membrane is a selectively permeable barrier (phospholipid bilayer with proteins and carbohydrates) that controls what enters and leaves the cell. The other statements are false: cellulose is in the plant cell wall (not the membrane), membranes occur in all cells (not just animals), and membranes are flexible/fluid rather than rigid.
