NEET Botany Cell Membrane MCQ Question
Which of the following statements about the cell membrane is correct?
The fluid mosaic model describes the lateral movement of proteins within the lipid bilayer.
The cell membrane is completely impermeable to all types of molecules.
The cell membrane consists of a rigid structure that does not allow for flexibility.
