"Cell membrane" Outermost layer surrounding the cytoplasm.
Answer:
The correct answer would be the cell membrane.
The plasma membrane or cell membrane is a semi-permeable membrane which forms the outer covering of the cell.
This membrane is made up of a phospholipid which provides it with its semi-permeable nature.
Due to its semi-permeable nature, it controls the movement of substances inside and outside the cell.
