Corbin Webb · Answer 1

Answer: C. The plasma membrane is a rigid, nonflexible structure.

Explanation: a rigid plasma membrane will not allow passage of molecules across the cell membrane, osmosis and diffusion will not occur if the plasma membrane is rigid.

the plasma membrane or the cell membrane is not rigid but selectively permeable to ions and organic molecules such as sugar, CO2 and O2 and regulates the movement of substances across cells.
