• B. It is the outermost layer of plant cells.
• C. Proteins are stacked between the lipid bilayer.
• D. It consists of a lipid bilayer.

Answer 1

Answer: (A), (C), (D)

It consists of a lipid bilayer.

Cell wall is the outermost covering in bacterial and plant cells. In the cells except bacterial and plant cells, plasma membrane is the outermost layer. Its structure consists of a lipid bilayer with proteins stacked in between. It is selectively permeable and allows few selected substances to pass through it.
